Overview

ISM01 soil moisture sensor uses VH400 sensor measures water soil content precisely and at low cost. ISM01 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.

Soil Moisture Sensors measure soil moisture with patented TDT (Time Domain Transmission) technology. ISM01 are self-calibrating for all soil types and conditions and are unaffected by salty soil conditions or soils with a high ph. ISM01 can be connected to a two-wire path or conventional wire and provide continuous measurements and real-time feedback for the controller to make smart irrigation decisions specific to the landscape the ISM01 is installed in.

Product Description

ISM01 soil moisture sensor uses VH400 sensor measures water soil content precisely and at low cost. ISM01 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.
ISM01 offers rapid response time in comparison to other water content measuring sensors. It can produce accurate result in a second as it inserted. ISM01 probes are long and slender and so they can be used in more applications than their bulky competitors, including monitoring of smaller potted plants
