Mobile phones have become one of the most popular communication devices among most of the people around the world, and short message service (SMS) is popular among mobile phone users as a cheap and convenient method of communicating. Therefore, SMS technology is a common feature with all mobile network service providers. Since the use of SMS technology is a cheap, convenient and flexible way of conveying data, researchers are trying to apply this technology in many different areas that were not provided by service providers at present. One of such areas that the SMS technology could be used as a cost effective and more flexible way will be remote monitoring and controlling. Therefore, a system has been developed to control and monitor electric circuitry through SMS using the PICmicroreg 16F877A microcontroller remotely. The microcontroller performs all the functions of the system. Standard attention commands are used to control the operation on SMS in the mobile phone. SMS is produced using the concept of protocol data unit. |
