PS-LB/LS-D
LoRaWAN Differential Pressure Sensor
The Dragino PS-LB/LS series sensors are LoRaWAN Pressure Sensor for Internet of Things solution. PS-LB/LS can measure Air, Water pressure and liquid level and upload the sensor data via wireless to LoRaWAN IoT server. The PS-LB/LS series sensors include Thread Installation Type, Immersion Type and Food Safety Thread Type, it supports different pressure range which can be used for different measurement requirement. The LoRa wireless technology used in PS-LB/LS allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

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.
