LSPH01 LoRaWAN Soil pH Sensor 868MHz

The Dragino LSPH01 is a LoRaWAN soil pH sensor for IoT in agriculture. It is designed to measure the soil pH value and soil temperature and send it over LoRaWAN. This allows the acidity or alkalinity of the soil to be recorded and analyzed. The LSPH01 probe consists of a solid AgCl reference electrode and a pH-sensitive electrode made of pure metal. It can determine the pH value of the soil with high accuracy and stable value. The LSPH01 probe can be buried in the soil for a long time. Applications include sensor network applications such as irrigation systems, smart metering, smart cities, temperature measurements, etc. The LSPH01 is powered by an 8500mAh Li-SOCI2 battery, designed for long-term use of up to 5 years. Each LSPH01 is pre-loaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server and the LSPH01 automatically connects after powering up if network coverage is available.
