RS485 Mini Soil Moisture, Temperature and EC Sensor: Modbus RTU, Soil and Substrate Monitoring, Bulk EC, Pore EC

The RS485 Mini Soil Moisture, Temperature and EC Sensor is an IP68-rated sensor for monitoring soil and soilless substrates. It measures volumetric water content from 0–100%, electrical conductivity up to 0–20 dS/m, and temperatures from -40 to 80°C. With a resin-sealed body, durable sensing rods, RS485 Modbus RTU communication, a wide 3.0–28 V DC power supply range, and low-power consumption, this sensor is designed for long-term and reliable soil monitoring. Built-in reverse polarity, TVS, and ESD protection enhance system stability, making it ideal for smart agriculture, greenhouse monitoring, irrigation management, hydroponics, and research applications.
