IOT Based Smart Home Security System

Abstract

The Internet of Things (IoT) helps to create safe cities, businesses, and homes by allowing both public and private organizations to remotely and securely monitor facilities. This paper presents an embedded framework for a smart home security system that uses a variety of sensors. As it emerges from conceptual models for the creation of security at various levels, the idea of Smart Security System is becoming a reality. IOT enabled with smart security system presents security to the home and also providing a facility to the user where one can continuously monitor the surrounding parameters inside the house (like gas, fire, voltage and motion intensity) and can control them by collection and exchange of data between the things for example switching on/off devices (like circuit breaker and gas valve based on these parameters). In recent days when ever house is locked the break-ins number has been increased enormously. So, in order to provide security to the home this presented paper is helpful. When the intruders enter into the house, image of the intruder is captured by the system, even if intruder escapes Police need to caught the intruder to recover the stolen things which needs the picture of the intruder to the police. The planned system captures the picture of the intruder and sends it to the authorized mail through internet over Simple Mail Transfer Protocol (SMTP). So, security to the home is provided more effectively in the smart way of communicating the things. Home appliances are smartly automated to reduce the human effort for intelligent decisions with the help of Internet of Things (IoT). This compact and lightweight product is designed to provide security and to control home appliances in the house by the owner through IoT servers. Microcontroller used here is NodeMCU ESP8266 for all processing and controlling operations. Various sensors such as Flame a Fire sensor, Gas, fire, PIR sensor with a magnetic door switch.
