Abstract

The global COVID-19 pandemic has highlighted the necessity for effective and contactless hygiene solutions to reduce the spread of infections. This research presents the design and implementation of an automated hand sanitizer dispenser system using Arduino Uno as the core controller. The system employs an HC-SR04 ultrasonic sensor to detect hand proximity and a servo motor to control the dispensing mechanism, ensuring a touch-free experience. The microcontroller is programmed to operate in a closed-loop system that activates the servo motor when a hand is detected within a specific range. Key hardware components include Arduino Uno, ultrasonic sensor, servo motor, jumper wires, and an uninterrupted power supply (UPS) for reliability. The software was developed using Arduino IDE, where custom logic was implemented for sensor input processing and actuator control. The system was tested under various conditions to ensure reliability, accuracy, and ease of use. Results indicate successful operation, demonstrating its applicability in homes, offices, hospitals, and public places. The study also explores future enhancements, such as integrating IoT features for remote monitoring and expanding the system for multi-functional sterilization. Overall, the system provides a cost-effective and efficient solution for personal hygiene automation.
