The Browan Ambient Light Sensor-915MHz is a LoRaWAN ambient light sensor that measures illuminance the way the human eye sees it. Useful for daylight harvesting, lighting control verification, greenhouse monitoring, and smart-building automation, it reports on light-level change over long-range LoRaWAN.
