The Dragino PS-LB-I sensors are LoRaWAN Pressure Sensors for the Internet of Things solution. PS-LB can measure Air, Water pressure, and liquid levels and upload the sensor data via wireless to the LoRaWAN IoT server.
The PS-LB series sensors include Immersion Type and Thread Installation Type (PS-LB-T), which support different pressure ranges that can be used for different measurement requirements.
The LoRa wireless technology used in PS-LB-I allows the 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-I supports BLE configure and wireless OTA update which make users easy to use.
PS-LB-I is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use for up to 5 years.
Each PS-LB-I is pre-loaded with a set of unique keys for LoRaWAN registrations, register these keys to the local LoRaWAN server and it will auto-connect after power on.
