Soil Moisture Sensor Details

Item Name

ISM01

Soil Moisture Sensor

Quick 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.

ISM01 offers rapid response time in comparison to other water content measuring sensors. It can produce accurate result in a second as it inserted.

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
