Induction

Streetlights use a tremendous amount of a city’s energy; the operation of these lamps can sometimes represent up to 60% of a city’s entire energy bill. Furthermore, current streetlight models are not optimized to be as energy efficient as possible. For example, most streetlights operate only on binary “on, off” settings, on a fixed schedule. There is now way to dim the lights during twilight hours to conserve energy.

Utilizing Semtech’s LoRa® devices and wireless RF technology (LoRa Technology) in a smart lighting application allows for remote lighting control to automatically adjust the amount of time lights are active, minimizing energy costs without sacrificing public safety. Smart lighting solutions also reduce maintenance costs, and being connected to the Internet of Things (IoT) means these utilities can connect with other applications for increased efficiencies. The interoperable nature of the LoRaWAN® protocol makes it easy to fit a smart lighting solution into a larger smart city network of applications which can monitor everything from traffic, air quality, and parking, to weather emergencies, and even gunshot detection.

Monitor parameters

All the electrical parameters are collected from the nodes and sent to the gateway, the gateway transmits the parameters to the web

In the dashboard we can observe all the parameters of the nodes of the same gateway. Timer to turn lights ON, OFF and dim directly in the dashboard. The feature of "add gateway" allows us to manage more node devices, up to 64 nodes for a gateway.
