PS-NB-NA
NB-IoT Analog Sensor
The Dragino PS-NB-NA is a NB-IoT Analog Sensor for Internet of Things solution. PS-NB-NA has 5v and 12v output, 420mA, 030v input interface to power and get value from Analog Sensor. PS-NB-NA will convert the Analog Value to NB-IoT wireless data and send to IoT platform via NB-IoT network. PS-NB-NA supports different uplink methods including MQTT, MQTTs, UDP ,TCP&CoAP for different application requirement, and support uplinks to various IoT Servers. PS-NB-NA supports BLE configure and OTA update which make user easy to use.

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.
