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 send it to the platform to analyse the acidity or alkalinity of the soil. 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 pH value of the soil with high accuracy and stable value. The SPH01-LB probe can be buried in the soil for a long time.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 extremely long range and high noise immunity with minimal power consumption.The SPH01-LB supports BLE configuration and wireless OTA updates, making it easier for the user to use.The SPH01-LB is powered by an 8500mAh Li-SOCI2 battery or a solar-powered + Li-on battery and is designed for long-term use of up to 5 years.E
