Introduction
We are living in a world where self security& for surrounding is utmost important. Conventional security systems like password, finger-print, thumb-print, palm scanning, Iris scanning could be breached easily. By knowing one’s password we can access system, and by force or by keeping one in unconscious state we can breach the remaining security system. So, the proposed security system allows us to address the protection of our document and offices/home with quality solution. The selection of voice as pass code is the best among all the techniques used for security.
System Requirements
Hardware
1. Microcontroller
Microcontroller is a compressed micro computer manufactured to control the functions of embedded systems in office machines, robots, home appliances, motor vehicles, and a number of other gadgets. A microcontroller is comprises components like - memory, peripherals and most importantly a processor.
DC Motor
A direct current (DC) motor is a type of electric machine that converts electrical energy into mechanical energy. DC motors take electrical power through direct current, and convert this energy into mechanical rotation
M moter Driver Circuit
Motor Driver circuits are current amplifiers. They act as a bridge between the controller and the motor in a motor drive. Motor drivers are made from discrete components which are integrated inside an IC. The input to the motor driver IC or motor driver circuit is a low current signal
Mic
microphone, sometimes referred to as a mike or mic (both IPA pronunciation: [maɪk]), converts sound into an electrical signal.Microphones are used in many applications such as telephones, tape recorders, hearing aids, motion picture production, live and recorded audio engineering, in radio and television broadcasting
HM2007 Module
Description: The HM2007 is a CMOS voice recognition LSI (Large Scale Integration) circuit. The chip contains an analog front end, voice analysis, regulation, and system control functions. ... A 40 isolated-word voice recognition system can be composed of external microphone, keyboard, 64K SRAM and some other components.
Relay
A relay is an electrically operated or electromechanical switch composed of an electromagnet, an armature, a spring and a set of electrical contacts. ... Relays are necessary when there must be electrical isolation between controlled and control circuits, or when multiple circuits need to be controlled by a single signal
Wireless Camera
Wireless cameras work by transmitting the camera's video through a radio (RF) transmitter. The video is sent to a receiver that is connected to a built-in storage device or through cloud storage. Through your monitor or receiver, you'll have an easy link to access all of your image or video clips.
B buzzer
A buzzer or beeper is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and beepers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.
Software
1. Embedded C
Embedded C is a generic term given to a programming language written in C, which is associated with a particular hardware architecture. Embedded C is an extension to the C language with some additional header files. These header files may change from controller to controller
A arduino IDE
The Arduino Integrated Development Environment (IDE) is a cross-platform application (for Windows, macOS, Linux) that is written in functions from C and C++. It is used to write and upload programs to Arduino compatible boards, but also, with the help of third-party cores, other vendor development boards.
