Air and water pressure sensor LoRaWAN Dragino PS-LB-T

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

Sensors of the PS-LB series include threaded installation type and immersion type , they support different pressure ranges that can be used for different measurement requirements.

The LoRa wireless technology used in the PS-LB allows the device to send data and reach extremely long distances at low data rates. It provides ultra-long range spread-spectrum communication and high immunity to interference while minimizing current consumption.

PS-LB supports BLE configuration and wireless OTA update, which makes it easy to use.

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

Each PS-LB is pre-loaded with a set of unique LoRaWAN registration keys, register these keys to the local LoRaWAN server and it will connect automatically after power on.
