Build a Micro:bit Earthquake Shake Detector That Warns of Tremors

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 small box that lights up and buzzes the moment the ground shakes — just like the early warning systems scientists use. Your child will assemble exactly that with this Micro:bit kit. They’ll turn a BBC Micro:bit into a portable earthquake detector, learning how accelerometers sense motion and how code can turn data into a lifesaving alert. Perfect for school science exhibitions, curious young makers, or a weekend project that blends earth science with real technology.

What You'll Build

You’ll create a compact, battery-powered tremor alarm. The Micro:bit’s built-in accelerometer continuously measures vibration; when shaking crosses a threshold set in code, the LED matrix displays a flashing warning icon and the piezo buzzer sounds. Kids can test it by gently tapping the table or shaking the kit and watch the alert trigger instantly. It’s a working model of how seismographs detect earthquakes, scaled down for a child’s desk.

What You'll Learn

• How to read accelerometer data using MakeCode’s drag‑and‑drop blocks
• Setting thresholds and using conditional logic to trigger a warning
• Wiring a piezo buzzer to create an audible alarm
• Basics of earthquake science and how rapid alert systems function

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Tailored for CBSE Class 5–7 students preparing for school-level science fairs or exhibitions. It’s also an ideal pick for ATL Tinkering Lab activities in Indian schools, where hands-on sensor projects build foundational STEM skills. Young makers in Hyderabad, Chennai, or Pune who’ve just started with block coding will find the project engaging and confidence-boosting right out of the box.

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.
