ABSTRACT

This project is one, which has a major part to play in the real world today meeting all

the electronic applications in an office.

The major attractions of the project titled SMART OFFICE are,

Counting of the number of person in a Room.

Room temperature display.

Temperature controlled Fan.

Light detector.

The counter section counts the total number of persons inside a room. The counter

automatically increments when a person newly enters the room and also it get decremented as

a person leaves the room. The counter counts from 0 according to the number of persons

entered into the room. Here the counting is just configured for having only a maximum of

100 people in the room and if necessary can be increased to any level.

The intelligence of the system automatically shuts down the light and fan inside the

room when the last person leaves the room security. Also the fan in the room works

according to the room temperature. That means if the room temperature is greater than 30

degree Celsius , the fan automatically turns ON. The light in the room automatically turns

ON, when there is insufficient light in the room.
