Introduction

• This Project helps to count number of visitors in a closed surrounding.

• Its working depends on the principle of intensity of light.

• This circuit counts the number of visitors entered and left and the result is shown in a 7 segment display

• Wastage of electricity is one of the main problems which we are facing now days. In our home, school, colleges or industry we see that fan / lights are kept on even if there is nobody in the room. This happens due to negligence or when we are in hurry. To avoid all such situations we have designed this project called “ Visitor’s Counter”. Main concept behind this project is to measures the number of persons entering in any room like seminar hall, conference room, classroom. This function is implemented using a pair of Counters. 7-Segment display placed inside the room displays the value of persons count. This persons count will be incremented if somebody enters inside the room.
