LoRaWAN Soil Moisture, Temperature & EC Sensor

The LoRaWAN Soil Moisture, Temperature & EC Sensor is an advanced solution for growers, agronomists, and environmental teams needing accurate soil data over long distances. Combining FDR (Frequency Domain Reflectometry) moisture measurement with temperature and salinity compensation, it delivers stable, high-accuracy performance across a wide range of soil types — including mineral, loamy, and saline-alkali soils.

This 3-in-1 probe continuously measures Volumetric Water Content (VWC), soil temperature, and electrical conductivity (EC), then transmits data via LoRaWAN to the ProSight Cloud Platform or your own IoT software.

Designed for Australian field conditions, the sensor includes an IP66-rated enclosure and rugged probe assembly. Powered by a long-life Li-SOCl₂ battery (4000mAh or 8500mAh), it supports multi-year unattended operation - ideal for farms, research sites, and remote monitoring locations.

ProSense holds local stock in Australia and provides full technical support, ensuring smooth integration and dependable long-term operation.
