Soil Temperature and Moisture Sensor

The Soil Moisture sensor analyzes accurately the occurrence, evolution, improvement and water-salt dynamics of saline soil. It is composed of a stainless-steel probe and a waterproof probe which can be buried in the soil to measure the surface and deep soil moisture, at the same time, ensures accurate and instant testing results. Soil sensors as an important tool for detecting soil health, provide data support for soil moisture monitoring, agricultural irrigation, and forestry protection industries
