The project describes an automatic room light controller with a bidirectional visitor counter with the help of Arduino Uno

This project's Digital visitor counter relies on communicating few components likewise sensors, motors, etc. with Arduino microcontroller.

This counter can calculate people in both directions. This circuit can be utilized to calculate the number of a person going in a home/office in the entry gate and it can calculate the number of persons leaving the hall by decreasing the count at the same gate or exit gate and it relies upon sensor placement in the hall. It can also be utilized at gates of parking areas and more public places.
