PS-LB-D09 LoRaWAN Differential Pressure Sensor

The Dragino PS-LB-D09 is a LoRaWAN-based differential pressure sensor designed to measure the pressure difference between two air pressure points instead of absolute pressure. This makes it ideal for detecting blockages, valve status issues, and airflow imbalance in pipes, ducts, and ventilation systems.

It features long-range LoRaWAN communication, ultra-low power consumption, and battery operation, making it suitable for both industrial and building automation environments.
