LoRaWAN Soil pH & Temperature Sensor – Long-Range Smart Agriculture Monitoring

This LoRaWAN Soil pH & Temperature Sensor provides accurate, real-time soil chemistry insights for farms, horticulture, irrigation systems, and environmental research projects.

Built with a solid AgCl reference electrode and a pure metal pH-sensitive electrode, the sensor delivers highly stable and reliable pH measurements suitable for long-term outdoor deployment. The fully sealed IP68 waterproof probe is designed for permanent burial, ensuring consistent performance across a wide range of soil types — including loamy, sandy, and saline-affected soils.

Using LoRaWAN long-range, low-power wireless communication, the device transmits soil pH and temperature data directly to your IoT platform, including ProSight by ProSense or any third-party LoRaWAN server. This enables growers, agronomists, and environmental professionals to make data-driven decisions about fertilisation, soil treatment, irrigation management, and crop optimisation.

Powered by a robust 8500mAh Li-SOCl₂ battery, the sensor supports multi-year autonomous operation (up to 5 years depending on uplink interval), making it ideal for large-scale field deployments or remote sites where maintenance access is limited.

ProSense stocks this sensor locally in Australia and provides full technical support, ensuring smooth setup, integration, and long-term reliability for your project.
