Automatic Hand Sanitiser Dispenser Kit with Arduino Uno + Sensor
Automatic Hand Sanitiser Dispenser Kit – Touch-Free Hygiene with Arduino Uno
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a hands-free sanitiser dispenser that springs to life the moment you place your hand beneath it—no taps, no pumps, no cross-contamination. With this Arduino Uno-based kit, you'll build exactly that: a smart home automation device that uses an infrared proximity sensor to detect a hand and a miniature servo to press down on any standard pump bottle. It’s a perfect entry-level project for young makers, school science exhibitions, or anyone wanting to promote hygiene at home or in a classroom.
What You'll Build
You’ll assemble and program a complete automatic hand sanitiser station. When your hand moves within a few centimetres under the sensor, a green LED lights up and the servo arm smoothly presses the dispenser nozzle, releasing a measured amount of liquid. Remove your hand, and the servo resets, ready for the next user. Mount it next to a doorway or on a study desk, and you’ve built a practical, contactless hygiene tool that works every time.
What You'll Learn
- How infrared proximity sensors detect objects and output signals
- Controlling a servo motor with Arduino’s PWM pins
- Reading sensor data and triggering actions in Arduino IDE
- Breadboarding a circuit and managing power with a 9V battery
