The WaterOptimizer® soils moisture sensor measures water content. The soil moisture sensor is calibrated to operate in all soil types from sand to clay.

The WaterOptimizer® soil moisture sensor is suitable for direct burial in the root zone up to 1,000 feet away from the WaterOptimizer irrigation controller.

The soil moisture sensor operates on 24 VDC and outputs a current signal 4-20mA linear with the volumetric water content. The soil moisture sensor is wired directly to the WaterOptimizer 300 irrigation controller using two wires, minimum 18 AWG of irrigation per day
