Iot Based Full Range Audio System With Gesture Control

The IoT-based full-range audio system with gesture control is a smart audio system that allows users to control music using hand gestures without physical touch. An ESP32 microcontroller works as the main controller, while an APDS9960 gesture sensor detects hand movements such as up, down, left, right, and near to perform functions like play/pause, next track, previous track, and volume control. The audio signal is processed using a 3-way active crossover and amplified by TPA3116D2 class-D amplifiers to drive a subwoofer, midrange speaker, and tweeter, producing clear full-range sound. The system is powered using a 12-0-12 transformer and voltage regulation circuits. This project combines IoT technology, gesture-based control, and high-quality audio output to create a modern and user-friendly sound system.
