The Dragino NSPH01 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.
NSPH01 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 NSPH01 probe can be buried into soil for long time use.
Narrowband-Internet of Things (NB-IoT) is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services. NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency, especially in deep coverage.
NSPH01 supports different uplink methods include TCP, MQTT, UDP and CoAP for different application requirement.
NSPH01 is powered by 8500mAh Li-SOCI2 battery, it is designed for long term use up to 5 years. (Actually, Battery life depends on the use environment, update period & uplink method)
To use NSPH01, user needs to check if there is NB-IoT coverage in the installation area and with the bands NSPH01 supports. If the local operator supports it, user needs to get a NB-IoT SIM card from local operator and install NSPH01 to get NB-IoT network connection.
