Abstract:
Energy saving methods vary and includes human action (manual operation) and
automation (programming). Depending upon the type, mode of operation can
significantly provide a unique way of saving energy. This research presented a
proposed smart energy saving system using a PIR sensor in a classroom; this uses
infrared (IR) remote control system to switch „on‟ or „off‟ an energy system in the
absence of human beings. Satisfactory results of signal transfer from the remote
control to the fan and light was achieved. The circuit consists of PIR and Temperature
sensors, and a microcontroller-based automation along with a temperature and motion
display using LCD to switch „on‟ and „off‟ fan and light circuits. An embedded
system was employed in constructing the energy saving system. Four different
softwares were used for the testing to authenticate the performance of the work. They
are Windows operating system (windows 7), Cadsoft EGLE software, Multism
software and Hyper terminal (arduino 1.6.3). The testing was done with an
intelligence signal at different stages. The test results indicated a successful
implementation of the work compared. The device is made up of two sensors, and a
time delay of 10mins. More than two sensors can be used to achieve more clearance
and a time delay of 60 seconds. The findings of this research will be very meaningful
to many stakeholders.
