The Dragino UV254-LB is a LoRaWAN UVC Radiation Sensor for the 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 it to the IoT platform via the LoRaWAN gateway.
UVC harms human health, and UVC lamps will lose efficacy after long use. With UV254-LB, the administrator can know if the UVC lamp is operated efficiently and make sure it won’t work at unexpected times.
The LoRa wireless technology used in UV254-LB 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 whilst minimizing current consumption.
UV254-LB supports BLE configure and wireless OTA update which make users easy to use.
UV254-LB is powered by an 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.
