Multi Layer Soil Sensor

This multi-layer soil sensor can continuously measure soil conductivity, moisture content, and temperature at different depths for a long time. The data is transmitted to the free cloud platform via RS485 signal for remote real-time monitoring. The whole shell is made of stainless steel, which is effectively waterproof and corrosion-resistant. Message us for detailed manual.

Multi-layer soil sensor

Multi-layer soil sensor is a device developed by our company that can measure soil parameters in different depths. It can dynamically observe the soil electrical conductivity, moisture and temperature status at different levels. This soil sensor can detect the minimum 3 layers, and the highest 5 layers soil EC, temperature and humidity status. The soil sensor adopts standard Modbus-RTU485 communication and supports secondary development.

The shell is made of stainless steel, black flame-retardant epoxy resin is completely sealed, acid and alkali resistant, and can be buried in the soil for long-term dynamic testing.
It is suitable for soil moisture monitoring, scientific experiments, water-saving irrigation, greenhouses, flowers and vegetables, grassland pastures, soil rapid testing, plant cultivation, sewage treatment, precision agriculture and other occasions.
