Earthquake Early Warning Seismograph
Arduino Earthquake Early Warning Seismograph: Detect, Log, and Analyze Seismic Events
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Construct your own real-time earthquake monitoring station. This kit combines a sensitive SW-420 vibration sensor with the precision ADXL345 accelerometer to capture both sudden jolts and subtle ground motion. It timestamps every event using a DS3231 RTC, displays alerts on an OLED, and logs complete vibration histories to a microSD card — exactly the architecture used in professional early warning networks.
What You'll Build
You’ll assemble a self-contained seismograph that continuously watches over your surroundings. When it senses unexpected movement, it immediately records the moment, estimates the event’s magnitude from peak g‑force readings, and presents the alert on a crisp OLED screen. All raw data, including three‑axis accelerometer values, are saved to MicroSD for offline analysis, giving you a tool you can deploy in a school lab, a village monitoring post, or a campus hackathon project.
What You'll Learn
- Calibrate a 3‑axis accelerometer (ADXL345) and set vibration thresholds for seismic detection
- Integrate an SW‑420 vibration sensor as a trigger and a DS3231 real‑time clock for precision timestamping
- Log structured sensor data to a microSD card and display live alerts on a 0.96‑inch OLED
- Write Arduino code that estimates earthquake magnitude from accelerometer peak values

Who This Kit Is For
Engineered for India’s undergraduate engineers — B.Tech ECE/EEE students building mini projects, Smart India Hackathon teams tackling disaster management challenges, and advanced hobbyists at IITs, NITs, VIT, and BITS. It fits directly into ATL Tinkering Lab curricula for senior secondary students exploring IoT and sensor networks.
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?
Our AI companion guides you through every connection and calibration step, and you can message us on WhatsApp for one‑on‑one support from our engineers.
Can this kit distinguish between a tremor and everyday bumps?
Yes, you’ll program dual thresholds: the SW‑420 filter ignores minor taps, while the ADXL345’s high‑resolution g‑force readings let you set fine‑tuned earthquake detection thresholds in code.
How accurate is the magnitude estimate?
It’s an educational approximation based on peak displacement, not a calibrated PMR seismograph. It teaches the logarithmic scale principles used by real networks and produces consistent, repeatable results for projects and demos.
Can I connect it to the internet for early warnings?
The kit is designed for local logging, but you can extend it with an ESP8266/ESP32 (not included) to push alerts via WiFi. The MicroSD data format is ready for cloud uploads.
