Dragino PS-LS-NA LoRaWAN Analog Sensor

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

The LoRa wireless technology used in PS-LS-NA 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 while minimizing current consumption.

PS-LS-NA supports BLE configuration and wireless OTA update, which makes users easy to use.

PS-LS-NA is powered by a solar powered + Li-ion battery; it is designed for long-term use for up to 5 years.

Each PS-LS-NA is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to the local LoRaWAN server, and it will auto-connect after powering on.
