Many times we need to monitor the person/people visiting some place like Seminar hall, conference room or Shopping mall or temple. This project can be used to count and display the number of visitors entering inside any conference room or seminar hall. This is a bidirectional counter  which means it works in a two way. That means counter will be incremented if person enters the room and will be decremented if a person leaves the room. LCD displays this value which is placed outside the room.

Question and answers about this project:

Question: Why you have used Infrared sensors to count the no of persons?

Answer: Advantage of using Infrared sensor is that IR rays are not visible to human eyes. Also IR rays are not affected by any other sources. e.g. If you use LDR as a sensor then it can be easily triggered by sunlight or any other sources of light.

Question: What is the maximum count that can be stored in this project?

Answer: As the microcontroller used is an 8 bit microcontroller. Maximum data is FF hex which is 255.
