Engineering Projects


This project is developed for the users to control Electric and Electronic devices through Cell phone messages. The user can control all the domestic appliances for example, Light, TV, Fan, Fridge etc.

Now a days most of the peoples use cell phone for communication. Controlling devices through wireless media becomes very popular. GSM technology is very powerful because it overcomes the limited range of infrared and radio remote controls.

The user can send message to a particular cell phone number used in the GSM kit from any place. The message is received through a GSM modem.

The received signal is sent to the microcontroller. The microcontroller is programmed to receive the message and executes the corresponding operation according to the message through drivers and relays.

The driver section receives the corresponding signal from the microcontroller and controls the relay section. Relays are used as electromagnetic switch. The relay section operates the corresponding device to on and off.
