ATL Decibel Meter Noise Pollution Kit
ATL Decibel Meter Kit: Map Noise Pollution on Your School Campus with Arduino
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn your school campus into a live science lab. This kit helps students assemble a portable decibel meter that captures real-time sound levels and displays them on an OLED screen, then fill in noise map worksheets to identify the quietest and loudest zones — from the library to the playground. It's fieldwork, electronics, and data analysis all in one 2-hour build.
What You'll Build
A handheld Arduino-powered sound level meter that shows instant decibel readings on its display. Once the meter is working, you walk through campus locations, note the values, and mark them on the included noise map worksheets. The result is a clear, colour-coded heatmap that brings physics concepts like intensity and environmental impact out of the textbook.
What You'll Learn
- How to interface a MAX9814 electret microphone with Arduino Nano and read analog sound signals
- Converting those analog values into approximate decibel levels using code calibration
- Displaying live sensor data on a 0.96-inch OLED screen with clear labels
- Collecting real-world environmental data and plotting it spatially on a noise map sheet

Who This Kit Is For
Designed for ATL Tinkering Lab students, CBSE Class 6–10 science projects, and school eco-clubs investigating noise pollution. It's a ready-to-use fieldwork kit that matches the curriculum on sound waves and environmental awareness — useful for Smart India Hackathon junior challenges, regional science fairs, or just a hands-on physics period.
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 on the kit box to open the AI companion; it knows every connection in this project. If you need a human, our team is also on WhatsApp for quick troubleshooting.
Can we use this kit in different parts of our school campus?
Absolutely. The whole activity is built around moving to different zones — library, canteen, classrooms, playground — and recording readings. The five noise map worksheets let you mark each location, so you can even compare mornings and afternoons.
Does the kit require soldering or special tools?
No soldering needed. All connections are made on the included breadboard using the jumper wires, and the Arduino Nano is programmed via USB. A computer is the only extra tool.
Will I understand the Arduino code that comes with the kit?
The pre-loaded code is commented line by line, and the AI companion explains each function — from reading the mic pin to mapping values into decibels and updating the OLED. It's a great way to learn how sensor code works without prior experience.
