Occupancy Based Lighting Control Strategy Using a Network of Motion Detection Sensors for Energy Conservation in a Building
Publication Date : 06/07/2020
In this work a system has been designed and deployed using PIR motion sensors and ESP8266 Wi-Fi Modules to detect the presence of any human body and through proper communication justifies the occupancy status in a building. There are four different units and each unit carries ESP8266 interfaced with PIR module. Three of these units were configured as Clients and one unit was configured as Server in this case. The Server collects the status of motion sensor of itself as well as from the motion sensors of all the client units deployed at different sites. Finally the server unit sends appropriate commands to control the lights by switching the relays. Final output was live streamed and plotting of occupancy status data can be seen on a Sci-Lab platform in laptop screen connected through Wi-Fi. This work aims to highlight an opportunity to create and implement an energy conservation plan within a building. The objective is to conserve energy by exploiting the state-of-art technology and to control lights installed in the corridors by deployment of occupancy sensors at potential sites. The system design was highly rugged, compact and plug-n-play type. Hardware prototype validated the work.
