Soil Moisture Sensors


The soil moisture sensor (SMS) is a sensor connected to an irrigation system controller that measures soil moisture content in the active root zone before each scheduled irrigation event and bypasses the cycle if soil moisture is above a user defined set point. Soil moisture sensors, like rain sensors, are considered rain shut off devices, but while rain sensors measure evapotranspiration rates, soil moisture sensors measure real time soil moisture.

Rain Bird SMRT-Y Soil Moisture Sensor

Rainbird’s SMRT-Y Soil Moisture Sensor Kit

It’s time for a little feedback from the roots. With the new SMRT-Y Soil Moisture Sensor Kit from Rain Bird, an irrigation controller is directly linked to the absolute moisture requirements of a site’s vegetation.

When the sensor detects dry conditions, the next scheduled watering cycle is allowed. If a site’s soil moisture level is above the threshold, the irrigation cycle is suspended. There are just two basic components an in-ground sensor and a user interface at the controller.
