Homemade watering timer. Timer for drip irrigation: purpose, types and features of DIY manufacturing

Possibility to use automatic systems irrigation for watering significantly saves time for summer residents. Even more convenient option when the system is turned on by the irrigation timer set for gravity systems or barrel. There are two types of timers: electronic and mechanical. Let's take a closer look at their features.

Pros of using a timer

Automation frees up time and makes the work of the farmer easier. Drip irrigation, sprinkling are excellent helpers, relieving you of the need for regular watering of the beds with a hose.

However, leaving the garden or greenhouse for a long time still does not work - the system needs to be turned on and off every few hours. The use of an automatic irrigation timer (controller) solves this issue. By programming the device, you will free yourself from the constant presence and control of the system throughout the season.

Photos of the watering timer give an idea of ​​its device. Modern timers can be controlled via mobile phone or the internet. The device operates on two conventional AA batteries.

Advantages of using the device:

• there are practically no failures in work;
• quickly and easily installed;
• economical water consumption;
• irrigation can be programmed individually for any plantings;
• the plants receive regular watering at the same time, which contributes to their optimal development.

What tasks does the timer do?

When deciding whether there is a need to purchase a timer for your landings, you need to understand exactly how it functions.

Timer for drip irrigation starts and stops water, controlling the system, even several lines for irrigation at the same time.

It can be turned on and off independently - a special sensor sets the soil moisture level. This allows the appliance to turn off automatically, say, when it rains.

It is very easy to install the timer with your own hands - it is connected to a pipe or an ordinary garden hose using a fitting.

Mechanical timer

This kind of controller is the easiest to use. It is turned on manually, and it turns off on its own - after the time specified by the owner.

The minimum run time is one minute, the upper limit is 120 minutes. The controller operates on batteries. The cost of a mechanical timer is low, while it has a long service life.

Electronic timer

Electronic controllers have a more complex structure in comparison with mechanical ones and the cost of these devices is higher. The irrigation process will be fully automated. Switching on and off occurs automatically, the device operates on batteries, as well as a mechanical one.

The owner can plan the work for a long time, the duration of watering is from a minute to two hours. First, the date and time are set, after which you can select the irrigation program that is optimal for planting.

Working principle and setting

All types of timers operate on the basis of a ball valve or a solenoid valve. The ball timer works from a barrel or in gravity systems (at low pressures). Can be used for irrigation through medical droppers.

Controllers with valves operate from a central water supply (pressure about 0.2 atmospheres). The multi-valve device allows you to organize several lines of simultaneous irrigation. It works from the mains.

When setting a timer for a certain period of time, remember one small, but important detail... Watering with a hose manually, the summer resident sees perfectly when the earth is completely moistened.

With drip irrigation upper layer soil remains dry, and moisture is concentrated deeper, at the roots. Not seeing this, I want to water more often, because the soil seems to still be dry.

In order to avoid flooding of plants, after digging the soil with a shovel, you need to make sure that the root zone of the plants does not have enough moisture and watering is really needed. If the ground is too wet, then the timer must be set to decrease the watering time.

Often in suburban villages during the day, due to active irrigation, the water pressure decreases. Installing an automatic timer will make it possible to organize watering in the evening and at night.

The timer will help automate watering in any area, be it several hectares, a greenhouse, or even one plant, freeing the owner from the obligatory presence on the site and vigilant control. You can safely be absent from the country for several days or weeks, knowing that everything is in perfect order with the plants.

Watering Timer Photo

Watering is one of essential conditions for the growth and fruiting of horticultural crops. This is especially pronounced in the conditions of little snowy winters and subsequent dry summers, since many people do not have permanent opportunity monitor the process of watering your personal plot. An excellent solution will become an electronic controller of irrigation, which, following the program laid down in it and relying on external factors, will independently perform the watering process.

Currently, there are several classifications of the irrigation controller, all of them, as well as types of timers, are listed below.

Classification of controllers by type of management

• Auto. This type of controller allows watering according to a given program. Also, using it, you can adjust the amount of water during drip irrigation. This controller is the most practical for greenhouses. An undoubted advantage is the ability to program on optimal mode glaze. A striking example of an irrigation controller is the popular S538 in our country. The equally popular ball ga 322;

• Manual timer. It must be monitored to supply water and control its distribution. That is why such timers are gradually becoming a thing of the past, giving way to an automatic controller.

Site classification of controllers

There are timers for watering the following areas of the estate:

1. Garden. Designed for the garden different kinds controllers. Here you can use: electronic, mechanical, automatic, ball and other types. Such controllers can be used when taking water from both the water supply system and from the barrel. A great model for the garden is the GA 322 or GA 319 ball controller.
2. Garden. For irrigation of the soil in the garden, it is customary to use a mechanical or electronic timer. An excellent solution is the palisad 66191 model, which has more than 15 irrigation programs. This allows you to set the desired water supply conditions for beds with different crops.
3. Greenhouse. Typically, plants planted in a greenhouse require drip irrigation. For these purposes, the aforementioned palisad 66191 is also perfect. It also has a drip irrigation program in its functions.

Classification by type of water supply

There are several types of controllers, which are classified according to the type of water supply.

1. Drip irrigation timer. At the moment, they are perhaps the most popular among their fellows. The drip irrigation controller eliminates the possibility of excessive water consumption and excessive soil moisture. Irrigation takes place in accordance with a pre-planned water supply scheme. The advantage of drip irrigation is that it delivers water slowly. With this irrigation, plants grow more rapidly. Also, in addition to moisture, you can supply various additives that are necessary for plants. An example of such irrigation controllers are the well-known palisad 66191, ga 322, ga 319, as well as raco of various modifications. Irrigation controllers of this type have a moisture sensor that can detect soil conditions and the presence of precipitation. If the soil is already wet or it is raining, this is detected by the moisture sensor and the water supply is not applied.
2. Ball irrigation controller. Available in two types: mechanical and electronic.

Ball controller

The mechanical timer has the advantage of being easy to operate. Before starting it, you need to set the time frame for watering the soil and the duration of the water supply.

Electronic, however, must be programmed for the date, time, and also install the necessary program, which is most suitable for a particular culture. The water is supplied using the pressure that the pump creates. The pump can take water both from the tap and from a reservoir or barrel. Palisad 66191 is a prime example of such a controller.

Additional timer functions

In addition to its main purpose, the following additional features:

1. Rain sensor. A similar device is installed when installing soil irrigation systems on open area... It captures the presence of precipitation in an amount from 3 to 30 millimeters. The irrigation pattern accordingly changes, that is, the mini sensor will not humidify during natural precipitation. Also on a similar sensor there is a delay timer, which is set in manual mode... The water supply valve will be closed after rain for the time you set.
2. Diaphragm pump. This device is mounted together with a timer or separately. It monitors the amount of water accumulated in the tank, and when a critical level is reached, it turns off the supply.
3. Soil moisture sensor. Such devices are installed in several places in the garden. They measure the moisture content of the soil. When a certain level is reached, the sensors send a signal to the controller, which in turn opens the tap. The moisture sensor is an indispensable device for irrigation systems if they are not constantly monitored by a person. The humidity controller allows you to save as much water as possible, because the tap of the water supply system opens only at those moments when it is really needed. When installing such a device, the irrigation scheme must be changed, as a rule, in the irrigation controllers, the sixteenth program is designed to work with moisture sensors.
4. Filter. It serves for additional water purification if water for irrigation is taken from natural reservoirs or septic systems.

All additional devices can be purchased together with the irrigation controller or separately. It will be much cheaper when purchasing all equipment for the installation of irrigation systems.

DIY controller design

If for some reason you do not want to purchase in the store, you can do it yourself. There are many DIY methods for assembling a timer, the most popular of which are listed below.

The simplest irrigation controller

The simplest irrigation controller is easy to DIY. This does not require any extra knowledge. All that is needed is a fiber, like the one used in kerosene lamps, and a container with a side height of 5-10 centimeters. The scheme of work is very simple. One end of the fiber sinks to the bottom of the container. After it is completely saturated, water will begin to drip from the other end. It needs to be placed over the plant that needs watering. In this way, the humidity level will be maintained. If you need more watering, you need to take a thicker fiber.

Also, a drip irrigation device can be built with your own hands from an ordinary medical dropper, the principle of which is known to every person.

Ball valve regulating device

For DIY manufacturing you will need the following materials and products:

• water tank;
• tap;
• plywood circle - 2 pieces;
• five-liter bottle;
• assembly glue;
• sewing thread.

To install the irrigation controller, the valve needs to be slightly modified. Instead of a handle for closing and opening the tap, a pulley must be installed.

1. The pulley is made from two plywood circles. They are glued together with glue. A sewing thread is wound on the pulley, so that the structure is reliable, it is necessary to make several turns.
2. To the second end of the cord, it is necessary to tie a balance and a compensator for its weight, that is, a container with water. The weight of the load must be selected so that it is sufficient for the crane to become a lever.
3. It is very simple to adjust the weight of the load. To do this, add the necessary components to the bottle with water and sand one by one.
4. Load compensator, that is, a bottle of water. To do this, a small hole must be made in its bottom. When the mass of the expansion joint decreases, the load will begin to pull the rocker pulley towards itself, thanks to which the crane will open.

It can be connected both to a container with water equipped with a tap, and to a water supply system. In the case of a container, its level should be higher than the surface of the ground with planted plants requiring watering.

In the case of plumbing, everything is a little simpler. Nevertheless, the location of the water supply line should be at least 1.5-2 meters above ground level. Otherwise, the ballast and the timer tank will not be able to function due to the lack of room for maneuver.

Arrangement of an electric timer

In order to make an electric timer with your own hands, you must have basic knowledge of electrical engineering.

All we need is an electric motor, a pulley and photocells.

• Instead of the crane handle, you must install a pulley;
• By means of a belt, it must be connected to the pulley of an electric motor installed in the immediate vicinity;

Electric motor

• The motor will turn on depending on the movement of the sun, this is what photocells are needed for, which should be adjusted to the movement of the sun or some other factor. You can also install a timer on the switch of the electric motor, which will start it at a certain time to open the water supply. And in the other - for closing, that is, the reverse operation of the engine will be performed.
• In no case should you use a powerful motor that is powered by a power line. An excellent solution would be a screwdriver motor, and in some cases even from toy car... It all depends on how tight the tap is to open and close.

The latter option is the most optimal in all respects, because with it it is possible to regulate the water supply for the irrigation line in the required volumes and for quite a long time, unlike the second option.

Everyone knows that it is almost impossible to constantly be at the dacha, we are all busy with various things. And often there is a difficulty associated with watering the garden plot. What to do in such a situation? You can solve this problem by assembling an automatic watering system with your own hands, which, without your presence in the garden, organizes watering of plants in the greenhouse and garden plot.

For this, it is necessary that the garden has a water supply system and an electric valve or a water tank plus an electric pump. Control over the automatic irrigation process takes place in two directions: a timer and a soil moisture sensor.

That is, when a signal from a humidity detector is received, an electric valve or an electric pump is turned on and in automatic mode plants are watered in greenhouse or garden until the humidity is sufficient or until the time set in the timer has elapsed. This saves the garden owner from constantly watering the plants with his own hands.

Greenhouse automatic irrigation scheme

The timer is assembled on microcircuits DD1 - DD3. In fact, it is a daily automatic timer. For example, by pressing the start button, the machine will water the area and exactly one day later it will repeat this operation again.

A generator of rectangular timer pulses with a frequency of 97 Hz is assembled on logical elements. These pulses are fed to the dividers DD2 and DD3 counters. At the output of 1 counter DD3, a logical unit signal appears once a day. Now, at both inputs of the DD1.3 element, log.1, and when log.0 arrives at any of these inputs, the output of this element will switch from logical 0 to 1.

This will create an impulse through elements C6 and R5, thereby resetting the DD4 counter. Zero at the output of the DD4 counter starts the multivibrator, which determines the duration of automatic watering.

The time is set by changing the resistance of the variable resistor R6. With the specified values, this period can be changed from 1 min. up to 20 min. If it is necessary to increase this interval even more, then in this case the capacity of the capacitor C7 should be increased.

The moisture sensor is built on element DD5.3. At high humidity, a logical unit is formed at its output, and at low humidity, zero, indicating that it is necessary to water the plants located in greenhouse or garden area... The sensitivity threshold is set by the variable resistor R7. As soon as log.0 appears at both inputs of DD5.4, log.1 is formed at its output, as a result of which the transistor switch supplies power to the pump or the electrovalve, thereby starting automatic watering of plants.

Do-it-yourself humidity sensor electrodes. They are a pair of stainless steel pins stuck into the ground not far from each other. There may be several such sensors that need to be placed in different places near plants garden plot or in a greenhouse. They should be connected in parallel with each other with a mounting wire.

Plant Watering Machine Parts

The CD4001 counter can be exchanged for the domestic K561LE5, and the CD4040 for the K561IE16, K561IE20. Diodes KD522 can be replaced with, KD103, KD521, KD102. As a relay, you can use a 12V automotive relay of the BSV1M1240 type. Any Zener diode for stabilization voltage 9 ... 10V.

Irrigation measures are one of the main conditions for obtaining high harvest, and it is the timer for drip irrigation that allows you to improve the system, as well as make it as easy to use and highly efficient as possible.

Timer for drip irrigation: purpose, types and principle of operation

There are several classifications that allow you to subdivide devices into several types.

Depending on the type of control, the watering timer can be presented:

• automatic control system. This timer is designed to irrigate according to a predetermined program. By means of such a device, it is allowed to regulate the amount of water consumed in the process of drip irrigation. This option belongs to the category of the most practical devices for greenhouse structures. An undoubted advantage is the ability to program the most optimal and efficient irrigation regime;
• manual or mechanical timer with the advent of automatic devices, it has become less popular. Such low demand manual equipment dictated by the need to control the device.

Depending on the site of use, the controllers can be applied:

• on the territory of garden plantings. Electronic, mechanical, automatic, ball and other types of devices can be used here. They are used for taking liquid from a centralized water supply system or a special container;
• on garden ridges, it is best to use a ball water controller, but mechanical or electronic timers such as raisad have proved to be no worse, which allows you to set optimal conditions water supply for ridges with different cultures;
• in greenhouse structures, the use of a drip irrigation system is required, which is equipped with an auto-controller.

Manual Watering Timer (Video)

Today it is used several types of controllers, classified by the type of water supply:

• drip irrigation with timer... The most popular and demanded option, completely eliminating the possibility of encountering excessive water consumption and excessive waterlogging of the soil. Irrigation activities are carried out in accordance with a well-planned water supply scheme. The advantage of this design is the slow flow of liquid and the ability to feed with liquid fertilizers. Controllers of a system of this design are characterized by the presence of a moisture sensor, which makes it possible to capture the condition of the soil;
• ball irrigation controllers can be either mechanical or electronic. The main advantage of a mechanical timer is its ease of maintenance and operation. Immediately before the launch, it is required to establish the optimal timing of irrigation activities and the duration of irrigation. Electronic devices involve programming the date, time, as well as the choice the required program which most closely matches botanical features the cultivated crop. Irrigation is carried out by means of the pressure generated by the pump.

The choice should be made depending on factors such as soil and climatic conditions, irrigated area and the type of plants grown.

Advantages and features of using a crane with a timer for irrigation

The timer allows you to solve the following tasks:

• providing irrigation with a given intensity and optimal frequency;
• prevention of waterlogging of the soil and decay of the root system due to the measured and slow supply of water;
• foliage prevention sunburn;
• providing local irrigation, which reduces the risk rapid growth weeds.

With all this, it is necessary to take into account some of the disadvantages of using:

• the use of a classic irrigation system connected to a centralized water supply and fan nozzles causes simultaneous activation and a noticeable pressure drop when using one standard timer;
• used tap water rather cold, which often causes hypothermia of the root system of too thermophilic garden-fence and flowering plants.

It is required to follow the connection procedure and use only high quality and reliable connection fittings that can withstand high pressure water. Otherwise, an uncontrolled spill of liquid may occur, which can cause flooding of plants and a strong overconsumption of water.

How to make drip irrigation with an automatic timer (video)

Making a mechanical water timer for DIY irrigation

Performing a simple device can be quite easy and with minimal cost time and Money do it yourself. At the same time, correctly performed homemade option, in most cases, does not differ much in functionality from finished, factory products. The response time of the water timer is determined by the action of the drop, and the tank performs the functions of ballast. Leaving the container, the liquid reduces the weight of the structure and the water supply starts.

The arrangement of the water timer is carried out using a barrel under water, a ball valve, a pair of sheets of sheet steel or plywood, a canister, construction glue and a spool of ordinary sewing thread. The uninterrupted functioning of the system will require some refinement of the ball valve in the form of attaching a small rocker pulley to the handle. Thus, it is possible to open the handle tilt valve.

The pulley must be built from a pair of identical plywood circles glued together with construction glue. If metal circles are used, then they are connected with bolts. A few turns of a strong cord are required to wind on the pulley. When constructing the arm, the lengths of the cord must be firmly fixed to the edges of the structure. A ballast weight must be attached to the free ends of the cord, which allows the lever to be brought into working condition.

Regulation of the mass of containers can be done by adding sand and adding water. You can also use metal chips or lead shot as a weighting agent. A container filled with water serves as a timer. At the bottom of such a container, you need to make a very small hole through which water seeps. The device is powered by installing a container with water for irrigation on a flat surface. Balance bottles filled with sand and water are suspended from a pulley by means of a cord.

• manufacturer Raco produces a whole line of timers, including mechanical and electronic models, which automatically shut off the water supply line. Such devices have a simple design and ease of use.

Electronic watering timer (video)

Irrigation timers are very widely used by both summer residents and small farmers in order to ensure correct and timely dosing of water for any plants. In addition to ease of use, such devices help to significantly save energy, time and money.

Greetings to Muscovites!
Finally, came to me new smartphone, which one there is camera, and I can do any reviews. Go! Today, for my colleague, a timer bought for Ali was received to automate watering in the country / garden. All the same, the century is 21 technologies, and there is no time (and who has the desire) to visit the dacha for watering. We do not touch on the part of water delivery to “consumers”, this is another topic, here we will talk about a timer that will open water and let it go to consumers. Go! Review supplemented! Please, under the cut!

I don't like a bunch of photos about tracks, packaging and so on. Everything arrived, and the whole, this is the main thing. So let's start with what arrived:


The product was purchased in another store, the link is lost. According to the link in the review, there is also an adapter for quick connection, but I either did not have it in the description, or the seller forgot to put it, it's not scary. So, what is available: the timer itself, the instruction, a pair of threaded connectors for connecting to the water supply.

What the timer can do (the most important and interesting):
16 programmable programs
Water pressure: max. 6 bar / 150 PSI
Water temperature: max. 40 degrees
Batteries: 2x1.5V AAA

The most important thing is that it holds some kind of pressure. The device will be operated connected to a container with water, water will flow by gravity through a drip system to consumers. I think it is possible to use it on the water supply, but it may be necessary to install a reducer so that the device does not break.


When assembled, the device looks like this. Definitely missing an adapter quick release hose. On the other hand, it will always be connected. Why take it off?


Everything inside is plastic, but the plastic is quite pleasant to the touch, thick and durable. Exactly what is used in garden supplies.


The lid is transparent. It is screwed onto the timer through a silicone O-ring, very tight, with a squeak. Creates an impression of reliability.


Everything is powered by two AA batteries. The opening hours are not yet clear, tk. the device was not in operational use. A bug was immediately identified, while I was twisting and photographing, the contact disappeared. Therefore, when installing in combat mode, it is better to additionally fix the batteries in the compartment.

Let's move on to the most interesting, setting. At first glance, everything is very complicated, there are many buttons, it is not clear what to do. We gradually read the instructions and try. Everything becomes extremely clear and into place.

How and what is set up?

The first thing we do is hit the Time button. Use the arrows ˄ and ˅ to set the current time, confirm each value with the Set button, and also select the day of the week.
Unfortunately, I deleted this photo, so I already have the next photo where you can turn the timer on and off with your hands, bypassing the programs.
Press the On button, use the arrows to set the operating time, press the Set button. The timer opened, the water ran. On current photo, time 14:53, the timer opened the "latch" for 15 minutes.


Let's move on to the most delicious program. We press the Prog button, we get into the menu for setting the irrigation programs, there are 16 of them, as stated with us.


What can be customized. Program number, start time of watering, operating time, number of operations, either every 2 days (as I understand it, from the day the program was created), every 3 days, or according to the schedule. Use the arrows to select the day, use the Set button to mark.

At first, while dealing with this contraption, I thought that I had not bought what I needed. how to water several times a day? Everything turned out to be simpler than simple. For example, a person wants to water 3 times a day, but a one-time switch-on is configured in the program?
Therefore, we need 3 programs out of 16.
1. 7.00 for 30 minutes on Mon, Wed, Fri, Sun.
2.15.00 for 30 minutes on Mon, Wed, Fri, Sun
3..21.00 for 30 minutes on Mon, Wed, Fri, Sun
That's it, the setup is complete, we grease the O-ring, screw on the lid and put the timer in its rightful place.

Measurements and device:

In the " idle move"The device consumes 1.1-1.2 mA.


When the valve is triggered, the current rises to 350 mA (0.35 A), and then drops again to 1.2 mA, while the valve remains open. Also, in the event of a power failure, the valve remains open.

Now let's move on to the very important point - internal organization... Comrade Muskovo explained:

<...>If inside is not ball valve, and the diaphragm is due to the pressure from the barrel, alas, this timer will not work, which has already been written many times on specialized forums. It is these green timers that come with both ball and diaphragm<...>

My situation is as follows: in appearance, there is still a diaphragm inside, tk. the crane mechanism in the end is definitely not visible. Moreover, after opening, the air is blown out without much effort.
All these prairies are associated with the opportunity to work this device with containers by gravity, according to some information, devices with a diaphragm will not open at low pressure. I invite you to delve into the topic in more detail in the comments.

Summary:

For those who missed, I repeat, the timer was just purchased, it did not work in combat conditions, but when checked, everything buzzes, closes, and does not let air through. Bought on Ali in another store, link in the review for an example! In the hands it creates the impression of a reliable and high-quality product. Overview not paid and goods not provided free of charge. I just decided to share with everyone, in my opinion, a good thing for automating routine processes before the coming irrigation season.
Thank you all for your attention! I plan to buy +192 Add to favourites I liked the review +68 +154
