Amruta Gesture Controlled Contactless switch

The increasing need for hygienic and touch-free control systems has led to the development of sensor-based automation in homes and industries. This project presents a Gesture Controlled Contactless Switch designed using the Arduino Nano, APDS9960 gesture sensor, and a relay module to operate electrical appliances without physical contact. The APDS9960 sensor detects gestures such as swipe-up, swipe-down, left, and right, converting them into digital commands for the Arduino. The microcontroller processes these gestures and triggers the relay to switch the connected load ON or OFF. The system enhances user convenience by enabling effortless control of devices even from a short distance, making it especially useful in environments where minimizing touch is essential, such as hospitals, laboratories, kitchens, and public spaces. The design is compact, energy- efficient, and low-cost, making it suitable for smart home applications. This project demonstrates how intuitive gesture recognition can be integrated into everyday electrical systems to improve safety, hygiene, and user interaction.
