The Dragino SPH01-LB LoRaWAN Soil pH Sensor provides wireless monitoring of soil pH and temperature for agriculture, greenhouse, research, and controlled environment applications. Its rugged IP68-rated probe is designed for long-term installation directly in soil, providing continuous insight into soil acidity or alkalinity and temperature.
Using LoRaWAN connectivity, the SPH01-LB transmits measurements over long distances while maintaining ultra-low power consumption. The sensor includes temperature compensation for pH measurements and supports user pH calibration, Bluetooth configuration, LoRaWAN remote configuration, and wireless firmware updates.
Powered by an integrated 8500mAh Li-SOCl₂ battery, the SPH01-LB is designed for long-term field deployment with battery life of up to five years, depending on configuration and transmission frequency.
