DRAGINO Sensor LoRa LoRaWAN pH Sensor SPH01-LB-EU868

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 analyze soil acidity or alkalinity. The probe is IP68 waterproof.

The SPH01-LB probe is composed of a solid AgCl reference electrode and a pure metal pH sensitive electrode. 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 provides extremely long range spread spectrum communication with high interference immunity while consuming minimal power.

The SPH01-LB supports BLE configuration and wireless OTA updates, making it easier for users to use.

The SPH01-LB is powered by a 8500mAh Li-SOCI2 battery or a solar powered + Li-on battery and is designed for long-term use of up to 5 years.

Each SPH01-LB is preloaded with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will automatically connect after power on.
