LoRaWAN Air/ Water Pressure Sensor
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.
