IoT based Security System using Raspberry Pi

Abstract

Nowadays, Internet of things (IOT) enabled smart system has entered into a golden era of rapid growing technology. The Internet of Things is a concept to make every system connected with the Internet. This concept can be used for home security in an effective way. In this paper, we developed IoT enabled system to send security alert to user/owner of the home and registered members through email whenever human intrusion detection in front of home door. IoT enable home security system consists of raspberry pi-3, pi-camera, PIR sensor, Microphone, Ultrasonic sensor, buzzer, doorbell button, LED/LCD screen and internet connection. This paper suggests two operating modes for home security. In the first mode, whenever any person motion is detected and that person presses doorbell button, then system will capture an image and decide the person is familiar or unfamiliar with the help of stored database. If the person is not familiar then system will alert through e-mail notification to the user and registered members by sending captured image, video and audio clip of that person. If the person is familiar then system will capture an image of that person and stored in the system. In the second mode, whenever any suspicious movement of person is detected in front of door by system, it will send email notification alert and also activates security warning alarm system installed at the door. The designed system provides security against intruder, using IoT platform.
