The Rainfall Gauge Sensor is used in agriculture for irrigation control. This agricultural sensor records and sends data to the controller about its water content or the amount of precipitation that has fallen. The controller can thus interrupt an active irrigation schedule as soon as a certain quantity of water previously configured in the irrigation controller has fallen.

The interaction of the rainfall gauge with the irrigation controller optimizes water consumption, thereby avoiding waste.




This rainfall gauge sensor for agriculture has filaments to prevent birds from landing on it and destroying it. It has a capacity of up to 214 cm2, is highly robust and collects precision data.

Connect the Rainfall Gauge Sensor to the Irrigation Controller

The controller receives information from the rainfall gauge sensor to pause the running irrigation schedule, when it is raining.

With the Maher App, you can also view all the data recorded by the rainfall gauge on your mobile, PC or tablet. It shows the amount of precipitation that has fallen, even if you’re not on the farm. The irrigation schedule can also be paused manually from your mobile.
