Automatic Hand Sanitiser Kit with Arduino Uno + Sensor
Automatic Hand Sanitiser Kit – Build a Touchless Dispenser with Arduino Uno & IR Sensor
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Create a fully functional touchless hand sanitiser dispenser that automatically activates when you place a hand underneath. Using an IR proximity sensor, an Arduino Uno, and a servo motor, you’ll build a hygiene machine just like those used in hospitals and public spaces. Whether for a school science exhibition, a home safety upgrade, or a first step into automation, this kit turns a ready idea into a working prototype in just a few hours.
What You'll Build
A complete hand sanitiser unit that senses an approaching hand and pushes a standard pump bottle to dispense liquid without any contact. The Arduino Uno processes the sensor input, drives the SG90 servo to press the pump, and lights a green LED for visual confirmation. Once assembled, the circuit runs reliably on a 9V battery, making it portable and ready to demonstrate anywhere.
What You'll Learn
- How to read an IR proximity sensor and trigger actions based on object detection.
- Controlling a servo motor precisely with Arduino PWM signals.
- Wiring and coding for a simple automation logic without blocking delays.
- Building a practical hygiene prototype from individual electronic components.

Who This Kit Is For
Perfect for CBSE Class 6-10 students exploring sensor-based automation for science practicals, and ATL Tinkering Lab mentors looking for a plug-and-play hygiene project. Parents introducing electronics at home will appreciate the solderless assembly suitable for ages 10+ with minimal supervision. B.Tech ECE/EEE first-year students can use it for introductory Arduino labs, and even Smart India Hackathon teams can prototype a contactless sanitation module quickly.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to launch your AI build companion trained on this kit; it guides you through wiring, code upload, and troubleshooting. Direct WhatsApp help is also available from our Bengaluru team within hours.
Does the kit include the sanitiser bottle or pump mechanism?
No, the kit provides the electronics to automate a standard press-down pump bottle. You supply any liquid soap or sanitiser bottle; the servo pushes it mechanically using a simple bracket (you can craft one from cardboard). Detailed mounting tips are in the build guide.
Can younger builders (age 5-10) assemble this kit?
Yes, with adult help. The instructions use colorful diagrams and pre-written Arduino code, and the AI companion offers voice-guided steps. Younger children learn cause and effect — hand near the sensor makes the motor move — while an adult handles the wiring.
What if the sensor detects false triggers or fails to dispense?
The AI companion will walk you through adjusting the IR sensor’s range using its onboard potentiometer and testing the servo angles in the code. Because every part is pre-verified, most issues are solved within minutes by repositioning the sensor or tweaking the code values.
