Cold Storage & Display Cases
For supermarket chillers, refrigerated display cases, cold storage deadzone detection, VAV terminals, and clean rooms.

SPH01-NB
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 or CoAP for different application requirement, and support uplinks to various IoT Servers.
Application guide

For supermarket chillers, refrigerated display cases, cold storage deadzone detection, VAV terminals, and clean rooms.

For HVAC supply or extract ducts, filter pressure-drop monitoring, and air handling unit performance checks.

For main duct airflow, fan outlets, compressed air systems, and industrial ventilation monitoring.
How it works
Deploy AirFlow-LN at critical airflow points, transmit measurements through a LoRaWAN gateway, and use platform data to detect weak airflow, filter problems, or abnormal ventilation conditions earlier.
