Voice Controlled Home Automation System

Home automation is developing to improve energy efficiency, convenience, and security. In this work, a voicecontrolled system that allows users to control appliances with speech commands is presented. An Arduino Uno serves as the microprocessor in the system, together with an HC-05 Bluetooth module for wireless connection and sensors like a fire sensor for security and an ultrasonic sensor for presence detection. An Android app's voice commands are sent over Bluetooth, processed by the microcontroller, and then carried out by relays. Furthermore, sensor-based automation makes it possible for automated reactions to changes in the surroundings. Accessibility is enhanced by this scalable and reasonably priced solution, especially for people with mobility disabilities. The implementation offers a user-friendly and effective interface for controlling smart homes and exhibits dependable performance.
