The Dragino UV254-LB is a LoRaWAN UVC Radiation Sensor for Internet of Things solution. UV254-LB is an indoor UVC sensor specially designed for detecting the intensity of ultraviolet lamps. UV254-LB will convert the UVC Intensity to LoRaWAN wireless data and send to IoT platform via LoRaWAN gateway.

UVC is harmful to human health, and UVC lamp will lose efficacy after long time use. With UV254-LB, administrator can know if the UVC lamp is operate efficacy and make sure it won't work in unexpected time.

The LoRa wireless technology used in UV254-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.

UV254-LB supports BLE configure and wireless OTA update which make user easy to use.

UV254-LB is powered by 8500mAh Li-SOCI2 battery, it is designed for long term use up to 5 years.

Each UV254-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.
