PS-LB-NA - Dragino LoRaWAN Analog Sensor support 0-20mA, 0-30V, 5/12V output

The Dragino PS-LB-NA is a LoRaWAN Analog Sensor for Internet of Things solution. PS-LB-NA has 5v and 12v output , 4~20mA, 0~30v input interface to power and get value from Analog Sensor. PS-LB-NA will convert the Analog Value to LoRaWAN wireless data and send to IoT platform via LoRaWAN gateway.

The LoRa wireless technology used in PS-LB-NA 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-NA supports BLE configure and wireless OTA update which make user easy to use.

PS-LB-NA is powered by 8500mAh Li-SOCI2 battery, it is designed for long term use up to 5 years.

Each PS-LB-NA 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.
