Abstract

In simpler terms, a smart street light is a type of street light that automatically adjusts its brightness based on the presence of vehicles on the road. The idea behind it is to save energy by reducing brightness when there's no need for full illumination. So, when there are no vehicles detected, the lights stay dim. But when a vehicle approaches, infrared sensors detect it and trigger the lights to brighten up, illuminating the area ahead of the vehicle. This helps in conserving energy while still ensuring safety and visibility on the road. As the vehicle passes by, the trailing lights turn dim automatically. Thus, we save a lot of energy When there's no vehicle activity on the highway, the smart street lights will stay dim, conserving energy by not using unnecessary brightness.

Keywords: Automation, smart light, power consumption, energy saving.
