Automatic lawn irrigation concept with products from akYtec GmbH

To create the right conditions for lawn care, an automatic irrigation system based on the Mini-PLC PR200 controller is suggested. The air temperature is measured by a DTS125L PT100 / PT1000 temperature sensor. The water pressure is fed to the sprinklers through the control valve is measured by a PD111 pressure transmitter. The system can also be equipped with a sensor that measures soil moisture. Water from the wells is collected in a storage tank. Irrigating is done by opening and closing valves according to the system settings. The water level in the tank is controlled by a two-level float sensor. A pump station, solenoid valves with sprinklers are needed to control the equipment. The irrigation pump is selected based on the water consumption of the system. The size of the area and irrigation requirements are significant in the selection of the pump station. The PR200 irrigation control algorithm considers air temperature and soil moisture. If the humidity is above the acceptable range, irrigation is stopped. Irrigation is not performed when the temperature is too low or high. The PR200 screen can display measured values (temperature, humidity).

The system can be additionally equipped with a weather station. The weather changes and the need for irrigation will be monitored. These systems allow you to monitor air temperature and humidity, wind direction and speed, as well as the amount of precipitation. A cloud service can be used to monitor and control the system remotely via PC or phone. A network gateway is connected to the PR200. The system can work both in automatic as well as in manual mode.
