Volumetric Water Sensor

Our AT200-SV soil moisture sensor probes enable precise low cost monitoring of soil water content.

Because our probe measures the dielectric constant of the soil using transmission line techniques, it is insensitive to water salinity, and will not corrode over time as does conductivity based probes. Our probes are small, rugged, and low power.

Probes come in standard cable lengths of 4 meters.
