Seismic Intrusion Detection Floor Sensor Variant 6 Kit with Arduino Mega
Build a Covert Floor-Based Seismic Intrusion Detection System with Arduino Mega
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit equips you to install an inconspicuous floor sensor network that detects footstep vibrations, logs events, and sends alerts via GSM. By embedding four ADXL345 accelerometers under tiles, you create a perimeter security system capable of distinguishing an intruder’s location from ambient noise—ideal for safeguarding server rooms, bank vaults, or private estates without visible cameras.
What You'll Build
You’ll assemble a multi-sensor seismic detection grid that captures vibration signatures through floor tiles. The Arduino Mega processes data from four accelerometers via an I2C multiplexer, applies threshold-based classification to identify intrusion direction and approximate zone, timestamps events with a real-time clock, stores logs on microSD, and triggers an SMS alert through the SIM800L GSM module. The build results in a standalone, low-profile box that can be buried beneath flooring—covert and reliable.
What You'll Learn
- Array processing of vibration signals from multiple ADXL345 sensors over I2C multiplexing
- Implementing footstep signature classification algorithms on Arduino Mega
- Integrating real-time timestamping with DS3231 and SD card data logging
- Configuring GSM-based remote alerts with SIM800L for security applications

Who This Kit Is For
Security system integrators, diploma and B.Tech ECE/EEE final-year students working on surveillance projects for Smart India Hackathon, and professionals designing covert perimeter protection for critical infrastructure. If you’ve completed a basic Arduino sensor project and understand I2C communication, this advanced kit pushes you into real-world multi-sensor data fusion and event classification. ATL Tinkering Lab facilitators may also use it for demonstrating industrial-grade embedded security.
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 box to open the AI companion, which provides step-by-step troubleshooting. If you prefer human help, reach out on WhatsApp for direct support from our team.
Can the system distinguish between a person and a pet?
Yes, the vibration signature classification algorithm can be tuned to filter out lighter, four-legged animal patterns from heavier human footsteps. The kit’s code includes adjustable thresholds for weight and gait.
Does this kit require external power supply?
The included LM2596 buck converter steps down a standard 12V DC adapter (not included) to the required 5V, and the board can also run from a 9V battery for portable testing. The final build is designed for permanent DC power.
How many sensors can I scale this to?
The TCA9548A multiplexer lets you add up to 8 I2C channels. You can expand beyond the initial four ADXL345 accelerometers if you have additional sensors and adjust the code. The kit provides the foundation for a larger grid.
ADXL345 accelerometers embedded under floor tiles detect footstep vibration signatures and classify intruder location.
