In today’s world, ensuring proper hygiene has never been more crucial, especially in public spaces where contact with surfaces is inevitable. The Automatic Hand Sanitizer using IR DIY STEM Kit offers a practical, hands-free solution to maintain cleanliness, reducing the spread of germs and viruses.

This innovative kit employs an IR sensor, LM393 comparator IC, and a water pump to dispense hand sanitizer automatically, ensuring a smooth, touch-free operation. The photo diode detects changes in light intensity, triggering the pump to release sanitizer only when hands are detected. The core principle behind this system is simple yet effective: when the IR beam is interrupted, the pump activates, allowing hands-free sanitization. Once the beam is restored, the pump automatically turns off.

What sets this DIY kit apart from other systems is its simplicity and affordability. Unlike most IR-based sanitizers on the market that are expensive and complex, this model uses readily available components, making it easy to integrate into various projects or spaces. Whether for personal use, public facilities, or educational settings, this kit enhances hygiene with minimal effort.

Applications of this system include automation, electronics, educational projects, and everyday hygiene use. Whether you’re looking to introduce a new project for a school, build an automation system for a business, or simply improve hygiene in your home, the Automatic Hand Sanitizer IR DIY Kit offers a cost-effective solution to suit your needs.
