In this competitive world human cannot spare his time to perform his daily activities manually without any fail. The most important thing he forgets is to switch off the room lights wherever not required. With this, even the power will be wasted up to some extent. This project gives the best solution for electrical power wastage. Also the manual operation is completely eliminated. The home appliances can be switched on/off using IR without actually going near the switch boards or regulators. The TV remote used in this project is IR remote. 

The loads like lights, motors, heaters, power controlling system and also current through the loads can be controlled in this project. We can control all loads at a time from one place (control room) without connecting any physical wire between loads and control room.

IR remote acts as the transmitter in this project. When a button is pressed in the remote, the signal will be passed and received by the IR receiver TSOP Receiver. This signal is sent to the microcontroller which decodes the signal and performs the corresponding action in accordance with the button pressed in the remote. For example, if number 1 is pressed in the remote, the load 1 will be switched on/off according to the user requirement. The other tasks will be performed in the similar fashion using IR.

This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.
