The Dragino SPH01-LB is a LoRaWAN soil pH sensor for IoT in agriculture. It is designed to measure soil pH and soil temperature and transmit the data to the platform to analyze the soil's acidity or alkalinity. The probe is IP68 waterproof. The SPH01-LB probe consists of a solid AgCl reference electrode and a pH-sensitive electrode made of pure metal. It can determine the soil’s pH value with high accuracy and stable readings. The SPH01-LB probe can be buried in the soil for extended periods.The LoRa radio technology used in the SPH01-LB enables the device to transmit data and achieve extremely long ranges at low data rates. It offers spread-spectrum communication with an extremely long range and high noise immunity, all with minimal power consumption.The SPH01-LB supports BLE configuration and wireless OTA updates, making it easier for users to operate.The SPH01-LB is powered by an 8500mAh Li-SOCI2 battery or a solar-powered + Li-ion battery and is designed for long-term use of up to 5 years.E
