Project report,ppt,basepaper for OTP BASED DOOR LOCKING SYSTEM USING GSM
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 modern 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. The codes for this project was written in assembly language with Visual basic software and compiled with M-IDE studio for MC-51compiler which work perfectly with Window XP environment, the program run without error before it was burn onto the microcontroller using a device called the programmer by placing the microcontroller on it socket equal to the pin number.The main purpose of this paper is to design and implement advance locker security system. In today’s materialistic world, security holds an in dispensable place. There is a need of security in almost every sector of society viz. offices, houses, banks etc. as thefts and robberies are increasing day by day. To overcome this security threat, a security system has been proposed using Controller and GSM technology. This system is basically a controller based accesscontrol system which allows only authorized person to access the locker with GSM technology. This system activates, authenticates and validates the user and then unlocks the door. It is standalone system controller is used to generate random password whereas GSM technology is used to send the password to the authorized person’s mobile phone via SMS.
