Abstract

This paper presents the design and implementation of an IoT-based smart home monitoring and control system using a NodeMCU firmware and prototyping board. The system allows the user to remotely control electrical appliances through a web-based user interface dashboard. The system uses sensors DHT11 to monitor the temperature and humidity of the home and MQ 2 to monitor the air quality and alerts the user in case smoke or fire is detected. Various HTML scripts are executed to develop a web-based dashboard interface where the user interacts with the system. When connected to the internet, the system generates an IP address that is used to assess the web page for monitoring and control of various house appliances. A maximum coverage range of up to 42.05 meters indoors was achieved by the system using the onboard Wi-Fi module on the NodeMCU. In addition, a correlation was observed between the Wi-Fi coverage distance and the response time to a command signal from the web-based dashboard. The system provides energy efficiency, home security, and centralized remote control of appliances thereby minimizing human efforts and energy losses and providing a friendly and secure home.
