Smart Room System Model Using a Microcontroller for the Efficiency of Campus Operational Costs

Internet of Things (IoT) is a concept that adopts an automatic control system or control that is done through a gadget. Currently the concept of IoT helps a lot in everyday activities. We sometimes forget to deactivate the electronic devices that have been used and the equipment is unwittingly active for 24 hours. That kind of conditions gives an impact on the cost of electricity bills that are increasing. It also disposes the resources of electric power. In this study it discusses how to make a smart room model using Arduino as a microcontroller. By adopting IoT concept, electronic device control is done automatically without a user having to press on / off button on an electronic device.
