ABSTRACT:
The main aim of this project is to control the appliances using gsm technology. The gsm is connected to our micro controller using rs232 cable. The appliances are interfaced to microcontroller through driver and relays. Whenever we send a message from particular mobile number which is used in the coding, our modem will receive that message and the appliances are controlled based on the message. So by using this system we can control the appliances from outside also through sending messages. We can also watch the appliance status using LCD display.
