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 and Immersion 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.

PS-LB/LS supports BLE configure and wireless OTA update which make user easy to use.

PS-LB/LS is powered by 8500mAh Li-SOCI2 battery or solar powered + li-on battery , it is designed for long term use up to 5 years.

Each PS-LB/LS is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.
