Abstract— We live in a time where many technological advancements are at our fingertips, our lives are made easier, which is fortunate considering the fast-paced lives most of us lead. In recent years, great strides have been made in making homes a bit more “tech savvy.” This technology, in short, allows the homeowner to run his or her home while away through remote, often on a Smartphone or iPad. In our project we presented a prototype implementation of home automation system that uses wifi technology as a network infrastructure connecting its parts. Previously Bluetooth module was used for this purpose which has reduced control since it covers small distance, high power consumption due to Bluetooth connectivity. We are using ESP8266 wifi module which is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your wifi network. For home security we are using PIR motion sensor which are basically made up of pyroelectric sensors which can detect the level of infra-red radiation. It almost always used to detect whether a human has moved in or out of the sensors range. These home automation systems provide increased comfort especially installed in private home. The conclusion of our project is to increase overall energy saving which is main issue today.
