SMS based Device Switching

Short Message Service (SMS) is defined as a text-based service that enables up to 160 characters to be sent from one mobile phone to another. In a similar vein to email, messages are stored and forwarded at an SMS centre, allowing messages to be retrieved later if you are not immediately available to receive them. Unlike voice calls, SMS messages travel over the mobile network’s low-speed control channel. Using the convenience of SMS, this project lets you remotely control equipment by sending plain text messages, such as "pump on", "aircon off", "reset" or "light1 on" – all of which can be pre-programmed into the controller and easily remembered later. It can control up to eight external devices. The 8 bit microcontroller is used to control the whole circuit. It read message from the Mobile phone and control the devices according the received message.
