Arduino Noise Pollution Logger Kit: Compare Classroom vs Playground Decibels

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 a school corridor into a citizen science station. This kit lets you build a portable decibel meter that automatically logs sound levels every minute, with exact timestamps. One afternoon of assembly and you'll be comparing the hush of the library against the roar of the road outside - all with a device you wired and coded yourself.

What You'll Build

A battery-powered sound logger that captures real-world noise data. The OLED screen shows current dB readings and log count on the spot. Every 60 seconds, the system stores a timestamped measurement in non-volatile memory, ready for you to transfer to a laptop and plot beautiful time-series graphs. You'll end up with a genuine environmental dataset, not just a blinking LED.

What You'll Learn

• Interfacing an analog MEMS microphone (MAX9814) to Arduino and converting its output into decibel values
• Reading date and time from a DS3231 RTC module and pairing it with sensor data for event logging
• Driving a 0.96-inch OLED display to show live readings and a running log count
• Building a field-ready instrument that runs on a 9V battery, then retrieving and analyzing the collected data

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for young tinkerers ages 10 and up, CBSE Class 11-12 students tackling environment-themed physics projects, ATL Tinkering Lab facilitators, and B.Tech first-year ECE/EEE aspirants prototyping a sensor logger. It fits perfectly into a Smart India Hackathon environmental challenge or a school's annual science exhibition. Even a curious primary schooler can assemble it with a parent's helping hand.

Built and Backed by Compoden
