Automatic Intelligent Home Appliance Control System

The popularity of home automation has been increasing greatly in recent years due to much higher affordability and simplicity through various available technologies. A home automation system integrates electrical devices in a house with each other. The main goal of automation is to reduce human effort and save power. The proposed technique is based on controlling the equipments by measuring the parameters of motion detector, temperature sensor, LDR and smoke sensor. The sensed signals are processed using signal conditioning unit based on the requirements. The microcontroller captures the entire signal and instructs the device to operate accordingly. The electrical equipment like light, fan, refrigerator and alarm are interfaced with microcontroller by suitable drive circuit. The microcontroller also derives an LCD to provide a simple user interface. The master control of the whole circuit lies in operation of magnetic switch which depends on opening and closing of the door.
