The smart street light will turn on when the vehicle passes through a particular LED pole.
When the vehicle is at LED pole no. 1 the IR Sensor will sense it and send the signal to the Arduino, which will Switch on the LED Light of that particular pole and next 2 poles.
Here we are switching on the next 2 LED poles so that the driver can see the path. As soon as the vehicle passes through the LED pole no.1 the LED of that pole will turn off.
The distance between the two LED poles is equal to the size of the vehicle.
This project will help in reducing the electricity consumptions.
