The Dragino SPH01-NB is a NB-IoT Soil pH Sensor for IoT of Agriculture. It is designed to measure the soil PH and soil temperature, so to send to the platform to analyze the soil acid or alkali level. The probe is IP68 waterproof.

SPH01-NB probe is made by Solid AgCl reference electrode and Pure metal pH sensitive electrode. It can detect soil's pH with high accuracy and stable value. The SPH01-NB probe can be buried into soil for long time use.

SPH01-NB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirement, and support uplinks to various IoT Servers.

SPH01-NB supports BLE configure and OTA update which make user easy to use.

SPH01-NB is powered by 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.

SPH01-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
