Here to learn, we will make a Arduino and Bluetooth based Visitor Counter and an Automatic Light Control System using Infrared sensor. In this project, a pair of IR sensors can detect the visitor IN/OUT directions, and arduino send these data to android application using Bluetooth. Android screen displayed in Visitor Walk In count, Visitor Walk Out count and Visitor inside count using android application. This device also have a Bar chart and pie chart for comparison of Visitor In, Out and Inside count for visual and data analysis.
In addition to that Visitor counter control an automatic light control system for ON/OFF for the light. If people presence inside the building the light automatically ON and If no people are inside the building the light automatically OFF.
