Description

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

Typical Resolution: 0.1%

Power: 3 mA @ 5VDC

Operating temperature: –40°C to +60°C

Dimensions: 8.9 cm × 1.8 cm × 0.7 cm (active sensor length 5 cm
