The Soil Moisture Sensor uses capacitance to measure the water content of soil (by measuring the dielectric permittivity of the soil, which is a function of the water content). Simply insert this rugged sensor into the soil to be tested, and the volumetric water content of the soil is reported in percent.
Specifications
Range: 0 to 45% volumetric water content in soil (capable of 0 to 100% VWC with alternate calibration)
Accuracy: ±4% typical
Resolution: 0.1%
