Smart Hand Sanitizer Dispenser Kit with Arduino Nano + Servo
Smart Hand Sanitizer Dispenser Kit — Build a Contactless Hygiene Project with Arduino Nano and Servo
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 sanitizer dispenser that squirts liquid without a single touch—just wave your hand and get the perfect dose. This kit turns that idea into a working gadget, blending hygiene awareness with the excitement of robotics. Your child will build a sensor-driven machine that mimics the contactless dispensers found in hospitals and malls, all while learning how IR sensors and servo motors work together.
What You'll Build
By the end of this project, you’ll have a fully operational automatic hand sanitizer dispenser. An Arduino Nano reads an IR proximity sensor; when a hand is detected, it commands the SG90 servo to press down on the included pump bottle. A green LED signals that the system is ready. The result is a real-world automation tool that promotes contactless hygiene in a classroom, at home, or in a science fair.
What You'll Learn
- How IR proximity sensors detect objects and trigger actions
- Controlling servo motor angles using Arduino PWM signals
- Reading analog sensor values and writing conditional logic
- Assembling a complete sensor-actuator system on a breadboard

Who This Kit Is For
This kit is perfect for CBSE Class 6-8 students building a science exhibition model on contactless safety, and for ATL Tinkering Lab members aged 10-12 who want a hands-on introduction to robotics. It’s also a great fit for young hobbyists curious about how everyday automation works and how to code simple sensor-driven behaviours.
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?
Open the QR code on the box to chat with our AI companion, trained specifically for this kit. You can also message us on WhatsApp for direct support from our team.
Does the pump bottle work with any sanitizer?
The included pump bottle fits the servo mount perfectly. You can refill it with any liquid sanitizer, but avoid thick gels that may clog the pump.
Is soldering required?
No soldering at all. All connections are made using the half breadboard and jumper wires, so the project is safe and mess-free for young builders.
Can I adjust the amount of sanitizer dispensed?
Yes, you can fine-tune the servo rotation angle in the Arduino code to control how much the pump presses, giving you a customised dose every time.
