Visitor Counter with Automatic light Control using IR sensor

Updated: Jun 14, 2021

In this project, we will make a Arduino based Visitor Counter with an Automatic Light Control System using Infrared sensor. The pair of IR sensors can detect the visitor IN/OUT directions and display presence of Visitor inside the building or store. The device counts the total number of people presence and automatic light. When no people are inside the room, i.e. the total number of people presence is zero then the room light is turned off.
