Watering timer - an overview of modern species. The principle of the timer, photos, instructions for proper installation.

At the cottage site a large number of devices are used that facilitate the process of courting the garden and lawns. We are talking about irrigation systems. Various types of sprinklers can be installed on the site, but their operation must be controlled.

To minimize human efforts in this direction, timers have been developed. They allow you to provide the best mode of applying moisture to the soil in different climatic conditions.

System benefits

People engaged in gardening and gardening do not always have enough time to constantly monitor the quality and completeness of hydration. After all, the duration of this process can be quite large. Therefore, timers for automatic watering are in significant demand.

Thanks to their use, you do not need to use hoses or control the on / off of the irrigation complex. And the amount of moisture that enters the earth will be sufficient.

The application of this approach provides summer residents with such advantages:

• more efficient water use for horticultural needs;
• automation of the spraying process;
• optimization of soil state parameters in terms of moisture, prevention of lack or excess of moisture;
• the ability to select the most suitable irrigation regime;
• network reliability and durability.

Principle of operation

The functioning of irrigation structures of an automatic form is based on hydrodynamic laws. This provides for the presence of gravity collectors. The water tank is placed at a height of 3-5 m. Pumping devices can be used to fill it.

Water is supplied to the channel from the tank without the action of pumps under the action of a small pressure. It is enough for moisture to flow to the beds. Timers for gravity-fed systems make it possible to ensure a rational water use regime and adjust the time and volume of the supplied liquid.

This device is threaded connected to a gravity collector and irrigation circuit. The design of a particular model affects the principle of operation. But its mechanism with a certain interval opens / closes the ball-type valve or press the valve at the solenoid. Water will be directed to the bed with a given frequency.

If you have a more complicated multi-circuit design, then installing a tank for gravity water transfer will be insufficient. You will need to buy and install a pump.

Mechanical control device

This type of device for regulating irrigation belongs to the budget class, but differs in a rather high reliability. There is no need for a permanent power supply. The valve is actuated using a special spring.

However, to turn on the mechanism, manual human intervention is required. Therefore, it is recommended to use it in combination with electromagnetic-type valves operating from batteries or electric control units.

This mechanism is suitable for semi-automatic irrigation systems. After a person turned on the device, it can turn off independently after a specified period of time - up to 72 hours.

You can apply this scheme in cases where the owner himself is on the site and can control the entire process of water intake.At a given moment, the mechanism is triggered, which leads to the overlap of the crane. You need to start the spring manually.

Mechanical electronic devices

Often the land plot is far from home. Therefore, the owner does not always have the opportunity to regularly visit him and set the watering regime manually.

In such cases, an electromechanical device will come in handy. It has the ability to tune for a long period - up to 7 days. The greatest duration of work is 120 minutes. At the indicated moment, the mechanism works and watering is carried out according to the planned scenario.

The timer for drip irrigation of this variety has the following advantages:

• affordable price;
• ensuring the automatic principle of the entire system;
• ease in setting modes;
• reliability and efficiency.

At the same time, additional control sensors cannot be connected to such a device, which makes it impossible to control the fluid flow.

To select the operating parameters you need:

• Open the cover.
• Use the left lever to indicate the frequency of starting. The maximum limit is 72 hours. The initial countdown is based on the activation time of the device.
• Use the right lever to set the duration of one-time spraying with a maximum step of 2 hours.

This option is suitable for processing large areas that are remote from the summer resident's house. Effective for field installation.

Intelligent Control Systems

Program control allows you to fully automate the irrigation process by setting additional parameters. It is possible to fix the regime for a long period of time, which is important for creating optimal conditions for the growth of plants in a garden or vegetable garden.

The number of possible software options can reach 16 units. The mode is selected for each type of culture. However, the high cost limits the use of a programmable tool in open fields without reliable protection.

You can additionally connect the following options to the device:

Rain sensor. Effective for installation in open space, since it takes into account the parameters of precipitation in the range of 3-25 mm. The signal is sent to the control unit, and the irrigation process is terminated. Humidification will not be performed during this period.

Sensor for tracking the fullness of the volume in the tank. Lowering the level to a critical level is the basis for automatically connecting a diaphragm pump to pump the right amount of fluid.

Soil moisture control sensor - allows you to optimize the microclimate in the soil. Excessive soil moisture or dryness is monitored. With this in mind, irrigation is becoming more frequent or limited.

Despite the fact that the kit includes special fittings and hoses, the problem of use is not the connection. Setting a timer for watering plants is difficult in terms of software configuration. To do this, you need:

• to disconnect a cover;
• activate the power button, for example Time;
• after the mode selection parameters appear, use the Set button to set the current time data;
• set work parameters for each day of the future period;
• Use the program selection item to specify additional options.

Each model has its own programming mode features. Therefore, you must first study the setup instructions.

Connection Features

Each type has its own specific settings and connections. Initially, you need to determine the type of irrigation and assess the possibility of access to your site.

Water supply mechanism

When controlling electronic devices, the method of mechanically controlling the moisture supply is important. For this purpose, an electromagnetic valve or a ball timer with a valve can be used.

The solenoid valve operates as follows. The coil is powered. In this case, an electromagnetic field is formed, which makes the core move inside the solenoid, blocking the movement of water. When the power is turned off, the core moves in the opposite direction, opening a gap for fluid movement.

But another, opposite principle of action is also possible. If there is no magnetic field, then the spring will force the valve to hide. The appearance of power turns on the feed system.

The action of the ball valve is based on the opening or closing of the gearbox. His work is set by an electric charge. When activated, the system starts. This can be determined by the characteristic noise of the engine together with the gearbox.

What to consider?

In the photo of the timer for watering, you can see its most diverse types and models. Connecting them is simple enough. However, two features should be considered:

Be sure to observe the correct connection in the direction of water movement. To do this, look at the entry / exit arrows on the timer.

The durability of the work depends on the quality of the water passed through. To avoid clogging with debris or large particles, it is imperative to install cleaning filters.

The use of these devices is most effective in single-channel gravity-type circuits. Nozzles are connected to the highway, from which spraying is performed along a given radius within the irrigation sector. A timer helps to control this process.

On large plots, a multi-channel principle is used with the connection of several network lines. Separate nozzles can be connected to each or special devices for drip spraying can be installed. But it is advisable in this case to use a pump.

The use of timers in irrigation networks can significantly improve the quality of care for the beds. Improving the microclimate in the soil contributes to the growth of crops. Also, the owners of cottages save resources, they do not need excessive physical effort to service their land plots.
