Seismic Intrusion Detection Floor Sensor Kit with Arduino Mega + LED
Seismic Intrusion Detection Floor Sensor Kit with Arduino Mega – Detect Footstep Vibrations and Classify Intruder Location
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Create a concealed floor security grid that identifies footstep vibrations and alerts you the moment someone steps into a restricted zone. Perfect for protecting server rooms, museum exhibits, or sensitive industrial floors, this kit uses four ADXL345 accelerometers placed under tiles to capture unique vibration signatures. The Arduino Mega processes those signals in real time, classifies the intruder’s location, and fires a GSM text alert through the SIM800L module while logging all events with precise timestamps.
What You'll Build
An embedded security system with four vibration sensors embedded in the floor, connected to an Arduino Mega via an I2C multiplexer. When footsteps disturb the tiles, the system triangulates the impact zone, shows the zone status on a 0.96-inch OLED display, saves event logs to a microSD card with date and time from the DS3231 real-time clock, and immediately sends an SMS alert with the intruder’s location.
What You'll Learn
- Interface multiple ADXL345 accelerometers on a single I2C bus using the TCA9548A multiplexer
- Process raw vibration data to distinguish footstep signatures from background noise
- Implement timestamped event logging with the DS3231 RTC and microSD module
- Configure the SIM800L GSM module for SMS-based intrusion alerts

Who This Kit Is For
Designed for security engineers, B.Tech ECE/EEE final-year students working on surveillance projects, and commercial property owners seeking a custom floor-based intrusion system. The multi-sensor vibration analysis and GSM integration align perfectly with Smart India Hackathon challenges and research labs in IITs, NITs, and VIT where real-time perimeter security is explored.
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?
Open the AI companion from the QR code — it understands this project specifics and can walk you through debugging. You can also reach us on WhatsApp for direct help.
Can I install the sensors under existing floor tiles?
Yes, the compact ADXL345 modules can be embedded beneath tiles or floorboards with minor drilling and adhesive. Our build guide shows installation methods for different floor types.
Does the system work with a battery for long-term field use?
The LM2596 buck converter lets you power the entire setup from a 12V lead-acid battery or a standard adapter. For extended deployment, combine with a solar panel and charge controller (not included).
How accurate is the intruder location classification?
By cross-referencing vibration peaks from the four sensors, the Arduino Mega triangulates which tile zone was triggered. The accuracy depends on sensor spacing; typical installations resolve zone areas as small as 0.5 square meters.
ADXL345 accelerometers embedded under floor tiles detect footstep vibration signatures and classify intruder location.
