DRAGINO · Sensor · LoRa · Air and water pressure sensor · PS-LB-I5-EU868

The sensors of the Dragino PS-LB series are LoRaWAN pressure sensors for Internet of Things solutions. PS-LB can measure air, water pressure and liquid level and upload the sensor data to the LoRaWAN IoT server via radio.
PS-LB series sensors include thread installation and immersion types, they support different pressure ranges, which can be used for different measurement needs.
The LoRa wireless technology used in the PS-LB allows the device to send 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 over-the-air OTA updates, making it easier for users to use.
PS-LB is powered by an 8500mAh Li-SOCI2 battery, designed for long-term use of up to 5 years.
Each PS-LB is pre-installed 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 on.
This sensor is intended for measuring water pressure in containers. If you want to measure air pressure in pipes, please use item 217627 or 217628.
