DRAGINO - Sensor - LoRa - Air and water pressure sensor - PS-LB-TG4-E -EU868

The Dragino PS-LB series sensors are LoRaWAN pressure sensors for Internet of Things solutions. PS-LB can measure air pressure, water pressure and liquid level and upload the sensor data wirelessly to the LoRaWAN IoT server.

The PS-LB series sensors include threaded installation and immersion types, they support different pressure ranges that can be used for different measurement requirements.

The LoRa wireless technology used in the PS-LB enables the device to transmit data and achieve extremely long ranges at low data rates. It offers spread spectrum communication with extremely long range and high interference immunity with minimal power consumption.

PS-LB supports BLE configuration and wireless OTA updates, making it easier for users to use.

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

Each PS-LB is preloaded with a set of unique keys for LoRaWAN registrations. Register these keys on the local LoRaWAN server and the connection will be established automatically after power up.

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