Utilization of Motion Sensors to Reduce Electricity Consumption in Buildings

Abstract

Electrical energy use at an agency that results in waste is a severe concern. One of them is in the toilet, which is often a waste of energy due to the lights being on while the toilet is not in use. As a result, energy waste is proportionate to an agency's monthly operating expenses. If waste can be eliminated, additional expenses will also be lowered. This study provides an algorithm that begins with the user pressing the push button to turn on the light and ends with the activated motion sensor. When a user enters the toilet and motion is detected, the toilet light remains on automatically. If, however, the user is not on the toilet after hitting the push button, the toilet light will automatically switch off after 60 seconds. Similarly, if the user exits the toilet, the toilet light will switch off automatically after roughly 60 seconds. The findings of a test conducted in a toilet for around two weeks using a motion sensor whose algorithm was optimized revealed a 7.08 per cent reduction in electric power usage after utilizing the equipment. Then, the device's test results indicate that the motion sensor detection is 100 per cent successful.

Smart Energy Public Street Lighting System

“…Therefore, the author intends to design and build a control system that can monitor an IoT-based public street lighting lamp that is accessed using an Android app and can adjust brightness and determine damage to public street lighting by utilizing sensors installed on public street lighting lamps. Electrical energy use at an agency that results in waste is a severe concern [10]. Intelligent control of public lighting is nowadays one of the most challenging issues in smart city deployment [11].…”
