PS-LB-D04 LoRaWAN Differential Pressure Sensor

The Dragino PS-LB-D04 is a LoRaWAN-based differential pressure sensor designed to measure the pressure difference between two air pressure points. Instead of monitoring absolute pressure, it helps identify pressure drops caused by blockages, valve issues, or filter clogging.

With long-range LoRaWAN connectivity, ultra-low power consumption, and industrial-grade design, PS-LB-D04 is well suited for both industrial and building automation environments.
