Every sensor has a specific function to control the electric appliances. Each sensor generates the signal and sends it to the relays and magnetic contactors which is directly control the electric appliance .this automation is control by a microcontroller circuit which connected to the computer by serial communication. In computer we can control all the system by using excels datasheet which is communicated with microcontroller. When system is activated by this technique we can control all the appliances instantly, as a change made in excel timetable. By this automation we can save a significant amount of energy and a lot of money.enBS ThesisElectric AppliancesMicrocontroller CircuitThesis
