Design and Construction of Door Locking Security System Using Global System for Mobile Communication (Gsm):- Nwagwu Silas C.
ABSTRACT
This
project presents a prototype security door that can be remotely controlled by a
GSM phone set acting as the transmitter and another GSM phone set with a dual
tone multi-frequency (DTMF) connected to the door motor through a DTMF decoder
interfaced with microcontroller unit and a stepper motor . The design is
composed of four main functional modules, namely; the GSM module, the decoding
module, controlling module and the switching module. The GSM module act as both
transmitting and receiving unit employs the use of a mobile phone set serving
as the communication device between the user at one end and the object of
access (i.e. the door) at the other receiving end. The decoding module and the
controlling module are made possible using modem integrated circuit chips
ensuring proper conversion of signal to binary codes, enabling the
microcontroller to communicate properly with the switching device responsible
for opening and closing the door.
