SPH01-NB - NB-IoT Soil pH Sensor

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. SPH01 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 measured values are uploaded wirelessly to an IoT Server via NB-IoT network.

You can use various IoT Servers and different uplink methods including MQTT, MQTTs, UDP and TCP. 

The sensor node uses Quectel BC660K-GL Multi-band LTE Cat NB2 module which can be used in most European countries. It has a card slot for an NB-IoT SIM card. Ask your mobile operator about availability of SIM cards, coverage, frequencies used and login procedures before you buy this product. See for example Deutsche Telekom IoT and 1NCE.

This device supports BLE for easy configuration and wireless OTA to update the firmware.

SPH01-NB is powered by 8500mAh Li-SOCI2 battery for many years of use. It has an external antenna and an IP65 enclosure with a waterproof external sensor.
