The Dragino LSPH01 is a LoRaWAN soil pH and temperature sensor designed for precision agriculture and long-term soil monitoring. It measures soil acidity or alkalinity (pH) and soil temperature, transmitting the collected data periodically to a LoRaWAN network for remote analysis and monitoring.
The sensor features a durable IP68-rated soil probe, suitable for long-term installation in soil, and an IP66-rated outdoor enclosure. Its pH measurement system uses a solid AgCl reference electrode and a pure metal pH-sensitive electrode, providing stable measurements with temperature compensation and user-supported calibration.
Powered by an 8,500 mAh Li-SOCl₂ battery, the LSPH01 is designed for low-power operation and a battery life of up to 5 years, depending on operating conditions and transmission settings.
