Abstract
Objectives: It is a common responsibility for individuals and organizations to effectively manage energy in buildings for economic and environmental concerns. In this study, the development of an energy management system integrated with a presence detecting sensor and an android mobile application for remote control of electrical appliances is undertaken. Methods/ findings: The integrated system is basically composed of a human presence detecting Passive Infrared (PIR) sensor mounted on a WeMos D1 microcontroller and remotely monitored and controlled from a web server using an android mobile application via a wireless network. The developed system provides multiple benefits. It eliminates human involvement and manpower often required to manually toggle power outlets and appliances on/off. Application: Furthermore, it conserves electrical energy and prevents wastages by ensuring that energy is only consumed when needed. The developed system is recommended for residential and small office applications. Keywords: Energy Management and Control, Android Mobile Application, Presence Detection Sensor.
Highlights
Electricity is a necessary requirement for everyday living as virtually all human activities rely on it for operation and effectiveness
The following materials were used in the realization of the system viz: (a) WeMos D1 micro-controller, (b) Passive Infrared (PIR) motion sensors, (c) Two-channel relay module
The system controlled energy supply to the power outlets in line with human presence detected by the PIR
Summary
Electricity is a necessary requirement for everyday living as virtually all human activities rely on it for operation and effectiveness These activities are commonly classified amongst residential and business lines. Absence of electric energy grossly affects the quality of life; the provision of adequate, reliable, and sustainable energy has always been both the focus as well as the challenge for electricity providers This challenge is commonly evident in the experiences of supply-demand imbalance and their undesirable effects [1,2,3]. Improper use of appliances and wastages contribute significant portions of consumed energy in residential and commercial buildings with that of the residential being 40% higher than the commercial buildings [4] This realization underscores the need for energy management in buildings
