2. Electricity is one of the most important resources in this country, the
electricity must be conserved, but many times people come outside
the room/hall forgetting to turn off the lights/fan, thus the electricity
is wasted.
The concept behind this project is to cut power supply when
there is no one in the room, thus reducing energy consumption.
STATEMENT OF PROBLEM.
3. Aims
This project aims at;
• Limiting power waste in schools, collages, offices and
conference halls.
• Making a controller which can sense if any person enters the
room and lights up automatically.
4. OBJECTIVES
• To design and construct an automatic room light controller
with bidirectional visitor counter.
• Incorporate transmitters, receivers and relay to detect the
presence and absence of persons and do the switching
automatically.
5. SIGNIFICANCE
This system will not only look at controlling the room light
circuit, it will also help to know the number of persons in a
room at a particular time.
7. LIMITATIONS
• Because it uses electricity, it will not work when there is
power outage.
• And also the counter can not detect when two people enter
at the same time.
8. METHODOLOGY
• Collect information on energy consumptions in schools,
colleges, offices and conference centers.
• The use of available component, taking into consideration
their cost and efficiency from manufactures, and the best
once suitable to this country.
