D20-NB/ D20S-NB
NB-IoT Waterproof /Outdoor Temperature Sensor
The Dragino D2x-NB is a NB-IoT Temperature Sensor for Internet of Things solution. D2x-NB has 1 ~ 3 temperature probes. D2x-NB will convert the Temperature reading to upload the sensor data send to IoT platform via NB-IoT network. The temperature sensor used in D2x-NB can measure -55°C ~ 125°C with accuracy ±0.5°C (max ±2.0 °C). D2x-NB supports temperature alarm feature, user can set temperature alarm for instant notice.

Application guide
Choose the airflow range by deployment scenario
0–5 m/s range
Cold Storage & Display Cases
For supermarket chillers, refrigerated display cases, cold storage deadzone detection, VAV terminals, and clean rooms.
0–10 m/s range
HVAC Ducts & AHU Verification
For HVAC supply or extract ducts, filter pressure-drop monitoring, and air handling unit performance checks.
0–30 m/s range
Industrial Ventilation & Fan Outlets
For main duct airflow, fan outlets, compressed air systems, and industrial ventilation monitoring.
How it works
Remote airflow monitoring via LoRaWAN
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.
- AirFlow-LN measures airflow in ducts, refrigeration, or ventilation points.
- LoRaWAN gateway receives data from distributed sensors across the site.
- Cloud platform visualizes trends and helps trigger maintenance decisions.
