Voice Recognition based Energy Efficient Control and Monitoring of Home Appliances through Android Mobile App using IoT

The suggested system aims to provide wireless control and monitoring of household equipment using a mobile application. Bluetooth-enabled home appliance monitoring and control is a reliable, low-cost, and simple technique; however, it is limited to a range of ten meters. The Internet of Things (IoT) provides an efficient home automation solution, allowing users to remotely manage household appliances and monitor sensor data via internet connectivity. The system is managed via an Android application created using MIT App Inventor 2, an open-source development tool. This app allows users to control home appliances like lights and fans by utilizing a Firebase web server. The implemented system can be operated via manual switches, the mobile app, or Google Assistant-based voice commands. Validation and verification of the system’s functionality were tested using Proteus 8.9 software. The proposed system simplifies wiring structures, reduces implementation costs and security risks, and enhances energy efficiency.
