When it comes to maintaining hygiene, many people turn to automatic sanitizer dispensers. But the challenge lies in finding an affordable, easy-to-assemble solution that is both reliable and efficient. Enter the Automatic Hand Sanitizer using IR DIY STEM Kit—a powerful, low-cost alternative to traditional, high-priced IR systems.

Unlike many IR-based systems that are complex and expensive, this DIY kit simplifies the setup by utilizing readily available IR sensors and a water pump. The core function of this system is detecting interruptions in the IR beam, which prompts the LM393 comparator IC to activate the pump and dispense sanitizer. The result? A seamless, hands-free solution to sanitization that’s easy on the budget.

But how does it compare to other options? Many automatic hand sanitizers on the market require expensive setups and extensive technical expertise. In contrast, this IR-based system is designed for DIY enthusiasts, students, and hobbyists, making it a great option for educational projects or home installations. Furthermore, this system operates on a 5V DC supply, meaning it’s compatible with a wide range of power sources.

Another key benefit of this kit is its ease of use. The assembly process involves simple soldering of components to the PCB, with clear instructions guiding you every step of the way. Once assembled, testing the system is as easy as connecting a power source and activating the IR sensor with your hand.

If you’re comparing different sanitizer dispensers or looking for a budget-friendly, hands-free solution to enhance hygiene, the Automatic Hand Sanitizer IR DIY Kit stands out as a practical, efficient choice. For more insights into its features and capabilities, keep reading!
