The Dragino SPH01-NB is an NB-IoT 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 acid or alkaline level. The probe is IP68 waterproof.
The SPH01-NB probe is made from a Solid AgCl reference electrode and a Pure metal pH-sensitive electrode. It can detect soil's pH with high accuracy and a stable value. The SPH01-NB probe can be buried into soil for long-term use.
SPH01-NB supports different uplink methods, including MQTT, MQTTs, UDP & TCP for different application requirements, and supports uplinks to various IoT Servers.
SPH01-NB supports BLE configuration and OTA update, which makes user easy to use.
SPH01-NB is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.
SPH01-NB has an optional built-in SIM card and a default IoT server connection version. Which makes it work with a simple configuration.
