Abstract—This paper presents the design and implementation of microcontroller based security door system (using mobile phone and computer set). The security door can either receive command through the mobile phone or through the computer system (configured to output data through the parallel port). Considering the high rate of crime and insecurity, there is an urgent need to design a security door that takes proper measure to prevent intrusion, unwanted and unauthorized user(s). To solve these problems associated with other security doors, the project uses a computer system running on visual basic (6.0), DTMF decoder and microcontroller as its main components to control the door. The result of these processes led to a security door which can be accessed by entering the corresponding keys of the assigned codes on the mobile phone, or by entering the corresponding code in a computer set interfaced with the system. The door opens automatically when the right code is entered and remains open for (10 seconds) before closing back. The designed system has been proven to be a reasonable advancement in access control and door security system technology.

Index Terms—dual tone multi – frequency (DTMF), global system Mobile (GSM), mobile phone, security door system.
