Vernier® Go Direct™ Soil Moisture Sensor

The Go Direct Soil Moisture Sensor is used to measure the volumetric water content of soil.

The Go Direct 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. This makes it ideal for performing experiments in courses such as soil science, agricultural science, environmental science, horticulture, botany, and biology.
