Retail Crowd Counter Kit with Arduino Nano + Servo
Arduino Nano Retail Crowd Counter & Contactless Sanitiser Kit
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 stepping into a store where a device automatically counts your entry and squirts sanitiser onto your hands — all without touching anything. This beginner-friendly kit lets you build that exact solution: an infrared proximity sensor detects a hand wave, the Arduino Nano signals a servo to press the pump bottle, and a green LED glows to confirm action. It’s a simple yet powerful introduction to automation, programming, and practical health tech.
What You'll Build
You’ll wire up the Arduino Nano, IR sensor, servo, and LED on the included half breadboard. Once assembled, you’ll mount the servo arm to press the pump bottle’s nozzle. Every time a hand is detected, the servo rotates down, dispenses sanitiser, returns, and the LED flashes — creating a contactless hygiene station that could be used in a real shop. The project demonstrates how retail analytics can be combined with safety measures, teaching both technology and social awareness.
What You'll Learn
- How to use an IR sensor with Arduino to read digital inputs
- Servo motor control for precise mechanical movement
- Arduino programming with loops, conditionals, and delay timing
- Building circuits on a breadboard and understanding pull-up concepts
