NETVOX Wireless Light Sensor R311G, the built-in photosensitive sensor, can be used for external ambient light intensity detection. Together with other devices to perform wireless dimming functions, and wireless communication meets LoRa protocol standards. R311G is the environmental illuminance automatic detector and the reporter which can send out the environmental illumination report and is a
low-power, long range, wireless sensor that can accurately detect environmental illuminance indoor.
Principle of Operation
R311G is able to read environmental illuminance over the LoRaWAN network, mainly used to detect the environmental illuminance indoor , which through the wireless network communication module to collect the data sent to the data platform displayed.
Example Applications
The device is universal an can be used for many applications. Ideally suited for a wide range of applications such as building automation, condition monitoring, predictive maintenance, security, healthcare and many more use cases. For example:
Home / Schools / Classroom / Reading room / Laboratory
Offices PC room / Working / Meeting room / Canteen / Restroom Factories Production hall / Laboratory, inspection work / Storage Hospitals / Bedroom / Entrance area / Restaurant / Bars / Staircases
