Abstract: The Contactless Switch Using Arduino is designed to enhance convenience and hygiene in controlling electrical devices by utilizing gesture detection technology. The system employs an APDS-9960 sensor connected to an Arduino for detecting hand gestures, which then trigger a relay to switch devices on or off without physical contact. This report details the system's design, working principles, advantages, applications, results, and future scope, providing a comprehensive overview of its functionality and potential benefits in various environments.
