Visitor counter using pic micro controller mini projects main idea is to implement a simple electronic application using sensors, micro controller and sensors to count total number of visitors inside room. This calculation is done by counting every person who is entering in to room and minus total number of persons leaving the room. Sensors are placed at entrance to count incoming and outgoing persons. Sensors will communicate with micro controller and program written in to microcontroller will calculate the total result based on these inputs and send to seven segment LCD display.

Code is written in c language and result is displayed on LCD screen. In this application we use PIC 18f452 micro processor.
