Automated Bathroom Lighting System Using HMMD mmWave Sensor

The Automated Bathroom Lighting System is a smart project designed for convenience, safety, and energy efficiency. It uses an Arduino UNO as the central controller with a Human Micro-Motion Detection (HMMD) mmWave sensor to detect human presence and micro-movements such as slight body motion and breathing, ensuring reliable detection even when a person is standing still. When someone enters the bathroom, the mmWave sensor detects the presence and automatically triggers the Arduino to turn on the light, eliminating the need for manual switches. After the person leaves, the system switches off the light automatically after a short delay, preventing energy wastage. The project is simple, cost-effective, and easy to build using basic components like Arduino, HMMD mmWave sensor, and an LED or bulb. It is suitable for beginners and provides a practical solution for common household problems. By ensuring lights are on only when needed, it reduces electricity consumption and promotes energy conservation
