Remote Monitoring and Home Security System

Security has been the most difficult task in recent years. The place where we retain our assets and capital is our home. However, we can never be certain that the asset behind us is secure. When we leave the house, we usually lock the doors. But simply shutting the door isn't enough; there has to be a system in place that keeps track of activities, reports to the owner, and works in accordance with the owner's reaction. Thus, the main motive behind the formulation of this paper is to develop a home security system which automatically notifies the neighbours using a buzzer alarm if it detects any unusual movement. The unusual movements are tracked using a Passive Infrared (PIR) sensor. The system also contains a mobile application which receives the alerts from the PIR sensor and in turn alerts the user on his/her cell phone. The system can also be continuously monitored with the help of the ThingSpeak IoT platform which is connected to the circuit using an ESP8266 module. The entire simulation of this Smart Home Security System is being carried out in the Autodesk Tinkercad environment.
