IoT Based Smart Home Automation and Security System Using Mobile App With Assistant Robot for Developing Countries

This paper discusses an IoT based home automation system through which home security, room air quality check, and emergency assistance can be obtained. This system can automatically provide home safety, but the user can also control the system manually if desired. The system uses the NodeMCU module as the mainboard and has a mobile application for remote monitoring. In addition to air quality detection, the system can detect CFCs used in the air conditioning system to avoid accidents. If any unwanted incident occurs, the system will immediately turn off the home's main power connection and send the house's status in the form of a notification to the user's mobile app. Also, an essential feature of the system is that the system is able to block the entry of any unwanted person in the house. There is also an assistant robot to prevent fire accidents initially.
