Smart energy saving system using a pir sensor in a classroom

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.
