Soil sensor is general term for monitoring soil moisture

Soil sensor is a general term for monitoring soil moisture, which can be divided into: soil moisture sensor, soil moisture meter, soil moisture meter, soil moisture meter, soil moisture sensor, soil temperature sensor, soil salinity sensor.

Soil water content can be expressed in two ways: gravimetric water content and volumetric water content (volumetric water content). The gravimetric water content was measured by the soil sampling and drying method, and the water content measured by the soil moisture sensor was the volumetric water content.

A soil moisture sensor is an instrument that measures the proportion of moisture in a unit of soil volume. Some soil moisture sensors can simultaneously measure three parameters of soil moisture content, soil temperature and total salt content in soil.
