Product information "DRAGINO · Sensor · LoRa · Air and water pressure sensor · PS-LB-TG4-B-EU868"

The Dragino PS-LB series sensors are LoRaWAN Pressure Sensor for Internet of Things solution. PS-LB can measure Air, Water pressure and liquid level and upload the sensor data via wireless to LoRaWAN IoT server.

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

PS-LB is powered by 8500mAh Li-SOCI2 battery, it is designed for long term use up to 5 years.

Each PS-LB 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.

This sensor is intended for measuring air pressure in pipes. To measure water pressure in tanks please use art. 217626
