Description :

R311G 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. 

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 other devices displayed. 


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. Netvox R311G is powered by batteries (2 CR2450 button batteries) with a life time of approximately over 5 years (depending on the usage and sending interval). 


LoRa stands for Long Range Low Power. With this technology small amounts of data can be transmitted to the internet. LoRa allows measuring illumination report on places that are hard to reach and with low power consumption. The device is compatible with any LoRaWAN network, such as the ThingPark Wireless. The LoRa connection to the internet allows widespread deployments.


It offers cost effective LoRaWAN end node solution for a variety of applications. It is reliable and its low power design allows a battery operation long life time. We hope to provide users an easy and comfortable way to monitor their surrounding and give their love one to be healthy and happy living.
