Rocket Noise Meter Kit with Arduino Uno + LED – Capture Launch Decibels on a Digital Display

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Step into the shoes of a rocketry sound engineer. This kit lets you build a portable meter that listens to the roar of a model rocket launch, instantly reads the sound pressure in decibels (dB), and freezes the highest peak on a crisp OLED screen – just like real launch monitoring systems. It’s a perfect fusion of space simulation, sensor technology, and hands-on coding for young explorers.

What You'll Build

You’ll assemble a complete sound level meter centred around the sensitive MAX4466 microphone and a bright 0.96‑inch OLED. After uploading the code, the meter displays real‑time dB values. The smart peak‑hold feature automatically locks onto the loudest moment – that split second of ignition – so you never miss the maximum noise. Enclose it in a custom case or mount it near your launch pad, and you have a genuine rocketry diagnostic tool ready for science fairs, ATL tinkering labs, or backyard missions.

What You'll Learn

• Interfacing an electret microphone amplifier with Arduino to read analog sound signals
• Converting voltage readings into decibel (dB) scale using a mathematical mapping function
• Driving a 0.96‑inch OLED display via I2C and rendering live sensor data
• Implementing a peak‑hold algorithm to capture transient high‑energy events like rocket launches

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for rocketry-curious kids and teens (ages 5‑15, with basic reading and fine‑motor skills), this kit fits seamlessly into CBSE Class 5‑10 science exhibition models on sound and space, ATL Tinkering Lab challenges, and weekend projects at maker spaces. It’s equally appealing to beginners who want to see sensor data come alive and to parents looking for a screen‑free‑coding‑plus‑electronics activity grounded in real‑world space science.
