Product Description

Product Description

 SEM2255 multi-layer soil parameter monitor is a kind of sensor which can measure multi-layer soil parameters. It can be used for dynamic observation of soil electrical conductivity, moisture content and temperature status of different layers. The detector can detect the temperature and humidity status of soil conductivity in three layers at least and five layers at most. It can quickly and comprehensively understand and collect soil parameter information. The product adopts standard modbus-rtu485 communication, which can communicate up to 2000 meters.
