Title:
MICROCONTROLLER BASED AUTOMATION
ABSTRACT
At homes, there will be various appliances to be operated according to our requirements and also based on the device’s constraints. For these purposes, a person should be employed to monitor the status of the loads. But there may be chances that the person may forget to operate these loads. And also it is not an easy task for a person to operate these loads manually as these loads run with high currents and high power consumption. This project gives the best solution for electrical power wastage. Also the manual operation is completely eliminated. This project does this application using wireless concept. One of wireless communication system is RF (Radio frequency) communication system as it is very cheap and very easy to implement.
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 will be switched on/off according to the user requirement. The other tasks will be performed in the similar fashion using IR.
