IoT based smart home for power & security management

The Technology is increasing day by day. Modern technology gives better solution to busy working people. Now a days, houses are equipped with variety of appliances like personal computer, switches, doorbells, Ovens, Televisions, LED lighting, Water heaters, HVAC (Heating, Ventilation, & Air Conditioning)etc. It becomes difficult to monitor all the appliances at a time. Sometimes if no one present at home & some appliances remains on, it will consume large amount of power and result's more electricity bill. This could be achieved by using modern technology like an IoT. Proposed work uses two sensors motion and temperature sensor. The PIR (Pyro-electric passive infrared) is used for authentication purpose, and temperature sensor LM35 is used for detecting current temperature of the room and accordingly operate the appliances present in the home.
