4. Output Options and Communication
This soil moisture sensor is available with multiple output options for flexible integration into different monitoring systems:
0 to 2V Voltage Output
Suitable for controllers and acquisition devices with voltage input.
4 to 20mA Current Output
Suitable for industrial monitoring systems requiring anti-interference analog transmission.
RS485 Modbus Output
Suitable for PLC RTU datalogger gateway and remote IoT monitoring systems. The manual states the default communication parameters are 9600 bps no parity 8 data bits and 1 stop bit, and parameters such as Modbus address baud rate protocol parity and stop bits can be adjusted.
5. Application Scenarios
This sensor is widely used in:
Precision agriculture
Smart irrigation systems
Greenhouses and tunnels
Soilless cultivation and substrate monitoring
Fertigation and nutrient solution monitoring
Flower and vegetable growing
Turf and pasture monitoring
Agricultural research and field trials
Soil condition monitoring
Environmental and water treatment projects
6.Installation and Measurement
For quick field measurement insert the probe vertically into undisturbed soil and avoid shaking during insertion to ensure close contact with the medium. For long term buried installation place the probe horizontally into the pit wall at the required depth and compact the soil after installation. EC readings are more representative when volumetric water content is above about 20% and after irrigation or rainfall.
