Energy Saving Assistance using IoT with Multi-function Nodes

This paper presents a device aims to assist energy saving in residential rooms. It can be used to control electrical devices using infrared or wifi controls to reduce the waste of electricity in abandon rooms. Infrared signals of various types and brands of electrical appliances such as air conditioners, televisions, fans can be learned and memorized for manual or automatic control uses. Users could promptly deploy the system with less installation effort. Automatic controls to turn off loads while no one is existing in a room is based on information from multiple types of sensors such as motion, temperature, light sensors. Energy monitoring, load controls also parameter setting can be done remotely through internet.
