The Dragino SPH01-LB is a LoRaWAN Soil pH Sensor for agriculture IoT. It is designed to measure soil pH and temperature and send the data to the platform to analyze the soil acidity or alkalinity. The probe is IP68 waterproof.
SPH01-LB probe is made by a Solid AgCl reference electrode and a Pure metal pH-sensitive electrode. It can detect the soil's pH with high accuracy and stable value. The SPH01-LB probe can be buried in soil for long-term use.
The LoRa wireless technology used in SPH01-LB allows the device to send data and reach extremely long ranges at low data rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
SPH01-LB supports BLE configuration and wireless OTA update, which makes user easy to use.
SPH01-LB is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use up to 5 years.
Each SPH01-LB is pre-loaded with a set of unique keys for LoRaWAN registrations, register these keys to the local LoRaWAN server, and it will auto connect after power on.
