The primary consideration in the present field of technologies is Automation, Energy. Night travel has always been troublesome and considered unsafe because of the lingering darkness. Consumption, and cost-effectiveness. Automation is intended to reduce manpower with the help of intelligent systems. Energy saving is the primary consideration forever as the energy sources are getting diminished for various reasons. As we all know that energy consumption has been increasing day by day so, to overcome these consequences we are using IoT devices. These traditional lights also have their pros and cons. These lights are switched ON and OFF manually. Hence sometimes mistakes happen. Like light remains ON even during the day. And by mistake sometimes lights remain OFF even during the nights. Street lights also run using the electricity supplied by the respective electric boards. And so when in the night, the supply is cut off due to any reason, the surrounding is completely engulfed in darkness as street lights and also the lights from our homes go OFF. This also leads to confusion and accidents. To overcome these shortcomings the idea of smart street lights was proposed. These lights are equipped with sensors, microcontrollers, etc. which makes this system smart. LDRs (Light Dependent Resistors) are the trigger to turn ON and OFF the smart street lights at Twilight. IR (Infrared) sensors sense the presence of vehicles and humans and switch ON and OFF the street lights in the dead of the night. LEDs are used in place of Sodium lights which are both energy and cost-efficient. Overall this system is costly to install but is profitable in the long run
