Automatic lighting management system based on working zone in office room by using visual motion detection from video camera on Android device

Abstract

This paper presents a design and development of automatic lighting control using image processing from Android phone or tablet in an office room. This work can make users conveniently to turn on-off lighting and to reduce energy consumption. For the operation of this work, the mobile phone installed in the best view try to detect moving object from video by using image processing. If the phone can detect the object, the command for controlling lighting will be sent to microcontroller via Bluetooth to control lighting switch via relay switch. Experimental is performed by varying the environmental lighting in the room from 70 LUX. to 45 LUX. The results show that the errors are 10%, 30%, 4 0 % for environment lighting in ranges 70 – 60, 60 – 55 and 55 – 45 LUX respectively.
