for Ceiling Fans with Bluetooth and Android Application
Peñas, Cherry Amor S. ,Villamor, Michael G. and Yuzon, Dexter C.
ABSTRACT
The design of
controlled switch for ceiling fans was formulated to answer the high power
consumption problem and high energy fee of the school. The automated switch for ceiling fans utilizes a temperature and motion sensor and can be access also by a
Bluetooth and Android Application. Any
Cooling appliances connected to this system can be switched ON/OFF through an
android application, Bluetooth, and the motion and temperature sensors. This
system is intended for Tologan Elem. School,Hagonoy, Davao del Sur.
The study aims to provide an alternative for switching ceiling fans and
other cooling appliances. To
help save and minimize daily electric consumption and can reduce the payment
for energy fee to the power distributor.

INTRODUCTION
Cooling
systems like electric fans and air condition are commonly used to provide a
comfortable environment. This regulates the temperature inside a close area,
thus reduce the accumulation of heat which add-ons to discomfort. Electric fans
make the environment conductive for any working activities. It helps to relax
and concentrate for any working people. It helps maximize the efficiency since
people can work well in a well-ventilated environment. Convenience is one of
the benefits that could get if the people are in a well-ventilated environmentcooling
systems are some of the appliances that provides the crave of the people to
experience a comfortable living.
One
way of managing power consumption especially in schools is to minimize the
usage of ceiling fans. By minimizing the usage of ceiling fans, this could
result to a decrease of the energy bill paid by the school.The researchers
introduced the automation of the ceiling fan utilizing temperature and
motion-controlled specially motion sensor and temperature sensor to address
this problem.
A motion sensor is a device that detects
moving objects, particularly people.
Temperature sensor
is a device that gathers data concerning the temperature from a source and
converts it to a form that can be understood either by an observer or another
device.
Automated Room
Lights Utilizing Motion Sensor is a study that utilizes a motion
sensor. This study is design to control the switching of the lights when motion
has been detected. The idea of using PIR(Passive Infrared) has been considered
through this study.
SCOPE AND LIMITATIONS
The project
covers the operation of a ceiling fan by triggering its operation mode when the
temperature reaches the triggering point just above the normal room ambient
temperature and when there is a person/s inside the room. 3 or more single fans
can be controlled by a single controller. The sensors to be used are a
temperature sensor and a motion sensor switch and have a digital display of the
temperature of the current room. The sensors also turns off the fan when the
temperature drops or cools down to its normal state. The ceiling fan would only
operate only if there is a person inside the room and the temperature should be
above the normal ambient room temperature (above 25̊C) and through an android
application. It can only maintained by technical person. Thus, it becomes
difficult to be maintained.
The project does
not control the speed of the fan. It has only two states which are the ON and
OFF state. The fan is to be in its standard speed when operating or if it is in
its ON state, and in OFF state when it’s not operating. The project uses only a ceiling fan.Motion sensor might not cover a
full room but not need to touch, push, pull, and press anything. Movement is
needed to detect. The ceiling fan would not operate (even if the temperature
reaches the triggering point) if there is no person on that classroom. This
system is only for Tologan Elem. School, Hagonoy, Davao del Sur.
2.OBJECTIVES
The main goal of this project is to control the improper usage of ceiling fans in Tologan Elem. School, Hagonoy, to minimize the power consumption of the school. Specific objectives of the project are defined as to save electrical energy consumption, to lessen the man power, to build a system that will automatically turn on the ceiling fan once motion is detected inside the room and when the temperature reaches above 25 ̊ C, the ceiling fan will automatically turn off when motion is not detected and the temperature is below 25 ̊ C and to incorporate a Bluetooth module to control the system by an android application.

. RESULTS AND
DISCUSSION
A supply of 6 volts DC is used to operate this circuit.
The major component in this circuit is the motion sensor module but it also
utilizes a temperature sensor, Bluetooth module and an android application. The
output of the sensors serves as an input to the Gizduino to encrypt the signal.
If there is a motion detected, the temperature above 25 ̊ C and a command from
the android application that switched on the ceiling fan, it will automatically
turns on the 220V AC fans. If the motion sensor fails to detect motion it will
automatically turned off the 220V AC fans. By properly installed and wiring it
correctly it will make the whole system more effective. This system can reduce
the power consumption of Tologan Elem. School.
