| Summary: | A lot of energy is wasted when lights, air-conditioning unit and other electrical devices are
still running without anybody inside the room. This situation frequently occurred at small
offices or classrooms when the last person leaving the room forgot to switch off the lights
and air-conditioning unit. A system which is able to detect the number of people entering
and leaving a room is developed to overcome this problem. The system has sensors
located inside, outside and at the door frame of the room entrance to detect the person
movement leaving or entering the room. When a person enters the room, the movement of
the person is detected and the counter of the controller will start the incremental counting
to record the number of person entering the room. Electrical supply of the room will be
automatically switched on at the moment the first person entering the room. When the
people inside the room start leaving the room, the counter will count downwards. The
electrical supply will be turned off automatically when the counter reaches 0. |
