Automated Light Control for IoT Application

This paper presents a practical implementation of Internet of Things (IoT) in daily activities. It is a common thing to depend on the manual process to control home appliances. Upon leaving home unattended, human might have forgot to check the operation of appliances. This leads to energy wastage and cost consumption. An automated light control system is developed with the aim to monitor and control lighting system, hence reducing energy and cost consumption. The lighting system is equipped with PIR motion sensor to allow automatic switching. It will automatically turn the light off around the room or area when there is no presence of human for an allocated time. Fail-safe options are available in two methods; by using a virtual switch in mobile application and also the physical switch accessible in the room. The mobile application will be displaying the energy consumption as well as billing monitoring in Ringgit Malaysia based on the electricity tariff set by Tenaga Nasional Berhad.
