- Introduction
Over
time, there has been a manual way of switching on/off of lights, among other
appliances like the air conditioners. At times people tend to forget to switch
them off and thus consumption continues in their absence. This has raised
electricity bills to the roof for victims of “electricity switching off
forgetfulness” syndrome. This system is intended to trigger switching on and
off of lights with presence/absence of a human being in a room respectively. This
does not exclude the exterior lights because similar to the internal lights,
people tend to forget them on during day and this hikes the electricity
consumption. To address this aspect, the system will automatically switch
lights on and off during night and day respectively. Furthermore the proposed
system will be in position to detect room temperatures and keep track of this
on a liquid crystal display and air-conditioner control incase the temperatures
rise way above the normal degrees.
1.1
Background
Currently
in most of the organizations in Uganda today, the process is like; someone
switches on the lights on entering a room but normally very few people remember
to switch off on leaving the room; this inspired us to come up with a system
that could do this automatically. Furthermore, we also got the idea of
extending the system to make it accommodate the external lights to the building
in a way that the outer lights would go off and on during day and night
respectively. For example; have you ever imagined why an air conditioner would
stay on in a room when there is practically no body in the room? Now with the
Auto-Tech system, which is aimed at reducing on the power consumption, the air
conditioners will be designed to only go on when there is an individual in
particular room and temperatures go above normal simply because it is
imperative not to have an air conditioner running in a room that has no
individuals occupying it at a particular time.
1.2
Problem
Statement
The
problem this project will address is to reduce on the cost of electricity by
switching on lights and the air conditioners when they are required and
switching them off when they are not required. This will also reduce on the
costs spent on human personnel to manage the lighting system in that the
application is to be developed in a way that it will switch on lights when someone
enters a room and switching them off when someone leaves a room. On the other
hand the system will also manage the outer/security lights so that when it
switches them off when during day and it also automatically switches them on
during night.
Furthermore
the system will be in position to manage temperature control by turning on the
air-conditioning system and alarming personnel in case of excessive or even
lethal temperatures.
1.3
Main
Objective
To reduce on the power consumption
costs by automatically switching off lights and the air conditioner control system
when not required.
1.4
Specific
Objectives
1.4.1
To ensure that the external lights to a
building are only switched on during night and they are kept off during day.
1.4.2
To ensure that the people are not
bothered to switch on lights when accessing a room and also not to forget and
leave the lights on when leaving a room.
1.4.3
To ensure safety of
personnel in case of AC failure and temperatures exceed the norm by triggering
an alarm to notify people of the danger.
1.5
Scope ( where applicable )
The scope provides for the boundary
of the research in terms of depth of investigation, content, sample size, methodology,
geographical and functionality coverage.
1.6
Significance
1.6.1
There
will be a significant reduction on the cost of electricity because there will
be no power consumption when a particular room is not in use.
1.6.2
This
system will also improve on the safety of the people by triggering an alarm
whenever the temperatures exceed the normal degrees.
1.6.3
There
will be efficient utilization of power by switching of security lights during
day and switching them on during night hours.
1.6.4
There
will be reduced employment costs, since the system will be monitored using
sensors to perform a particular task which will reduce the cost of human
employment that are responsible for monitoring the lighting system.

1.3
Objectives
1.3.1 Main Objective
The
main objective of this project is to reduce on the power consumption costs by
automatically switching off lights and the air conditioner control when they
are not required.
1.3.2
Other
Objective
·
The other objective of this system is to
ensure that the external lights to a building are only switched on during night
and they are kept off during day.
·
This system is also to ensure that the
people are not bothered to switch on lights when accessing a room and also not
to forget and leave the lights on when leaving a room.
·
The system will also be
designed to ensure safety of personnel incase of AC failure and temperatures
exceed the norm by triggering an alarm to notify people of the danger.
2.0 Methodology
The
methodology used to achieve the stated objectives is to use an embedded system that
will run on an arduino board that will control the other components like the
PIR motion sensor to detect presence of human personnel in a room via infra-red
radiations and a photo-resistor that will detect the darkness/light and switch
lights on/off respectively in this case simulated using RGB LED CA lights. The
embedded code will be written and run on an arduino micro-controller. Temperature
will be monitored by the temperature sensor which will then display the
temperature on an LCD, if temperatures are in excess the microcontroller should
be in position to turn on the motor fan to start blowing and cool the
temperature. The will also be use of a buzzer to alarm incase of high
temperatures (in case of probability of AC failure - hardware inhibition) with
intention to alert personnel of possible mayhem. The feasibility study and data
collection will be carried out by visiting different premises of the different
organizations and observing how their lighting system is designed and how their
air conditioning systems work.
3.0 Outcomes
The
out come of this project will be an Auto-Tech system that will ensure a
reduction on the power consumption where by the lights and air conditioners in
a given building will be automatically controlled with out any one having to keep
watch and switching them on and off where necessary.
The
other outcome of this system will be an improvement in the safety of the people
incase of high temperatures (possibly as a result of fire).
