Embedded Linux based smart security system using IoT and raspberry pi processor

Abstract

The project aims at designing an intelligent access control system based on finger print technology. the propose system make use of finger print module for authentication process and an electromechanical relay switch to control door locking system for door accessing. The system also supports with camera based image capturing technique when any wrong finger print was detected and alerts through email from wireless Wi-Fi connectivity.

The raspberry pi processor is a low cost, credit -card sized computer that can be used in electronics projects. It is capable device that enables people of all ages to explore computing, and to learn how to program in languages like scratch and python. It is capable of doing everything you would expect a desktop computer to do, from browsing internet and playing high-definition video, to making spreadsheets, wordprocessing and playing games.

In this project we make use of a finger print module, Wi-Fi module, and raspberry pi processor. The processor reads the input from the finger print module and when the authentication details are correct then the system automatically opens the door lock and closed after predefined time using relay switch. The database of the operation of the door along with timings gets stored in pc application using Wi-Fi wireless communication. The system also captures the image of the user who provides wrong authentication of finger print and sends alerting message with image to the predefined email using Wi-Fi wireless communication to pc application.
