A low-power and low cost smart streetlight system based on Internet of Things technology

Street lighting, as the most essential and universal component of urban lighting system, accounts for a large portion public electricity usage. Therefore, improving street lamps working efficiency is vital energy savings. This paper demonstrates design smart system supported by combination NB-IoT LoRa communication technology. By adopting an optimized lamp control algorithm, can realize automatic lights according to real-time traffic flow information. has been installed on Luyang Avenue, Lucheng City, Shanxi Province, China in May 2019. It managed reduce consumption this region significantly June 2019, which was 18% lower than that April 2019 19.7% 2018. illustrating unique advantages savings cost reduction, displays its potential further application construction cities scale.
