30 30  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.
31 31  
32 +
32 32  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.
33 33  
35 +
34 34  PS-LB supports BLE configure and wireless OTA update which make user easy to use.
35 35  
38 +
36 36  PS-LB is powered by **8500mAh Li-SOCI2 battery**, it is designed for long term use up to 5 years.
37 37  
41 +
38 38  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.
