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.
