A foreign farm wants to establish an automated irrigation system to realize an automatic watering system for farmland. It senses environmental conditions, monitors soil moisture, temperature, rainfall and other parameters, and automatically controls water pumps, valves, sprinklers and other equipment according to preset watering needs and plans to achieve regular and quantitative watering of crops.

The main working medium of the automatic irrigation system is water, so the water pressure of the entire system must be controlled to ensure the normal operation of the entire system. The pipes are outdoors, the power supply is inconvenient, and the entire irrigation scheme adopts the spray mode, which requires high power consumption and protection level of the sensor. When the automatic valve of the spray system is closed, there will be water hammer phenomenon in the pipeline, which will cause damage to the sensor.

By learning the customer's site situation and functional requirements,we recommended customers to use GPT200 pressure sensor transmitter series products, which adopts liquid level outlet and IP68 protection level to prevent damage to the sensor caused by the spray process or water immersion. In view of the customer's pipeline water hammer phenomenon, the sensor liquid inlet hole is damped to prevent the product damage caused by instantaneous high pressure. GPT200 water pressure transmitter uses 3.3V power supply and 0.5-2.5V output low power consumption mode. It is connected to the wireless transmission module, and the signals from other sensors are transmitted wirelessly to the customer's control platform to realize automatic control and monitoring of the irrigation system.
