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.
