The PS-LB series includes both Thread Installation Type and Immersion Type sensors, which support different pressure ranges for various measurement requirements. The LoRa wireless technology used in the PS-LB series enables the device to transmit data over extremely long ranges at low data rates, providing ultra-long range spread spectrum communication and high interference immunity while minimizing current consumption.

Additionally, the PS-LB series sensors support BLE configuration and wireless OTA updates, making it easy for users to use and update the sensors.

The PS-LB series sensors are powered by an 8500mAh Li-SOCI2 battery, which is designed for long-term use of up to 5 years. Each PS-LB sensor is pre-loaded with a set of unique keys for LoRaWAN registrations, and users can register these keys to their local LoRaWAN server for automatic connection after power on.
