About this project

Piezo-Based Visitor Sensing Welcome Mat

Objective: To develop a welcome mat that senses visitors using piezoelectric sensors and provides a visual or audio alert.

Context: Affordable, non-intrusive visitor detection systems are valuable for Indian households and small businesses seeking simple security or automation solutions. Piezo-based mats offer a low-cost alternative to complex camera-based systems.

What you'll build: You will calibrate piezoelectric sensors, design signal conditioning circuits, and program a microcontroller (Arduino or 8051) to trigger a buzzer or LED display upon detecting a step. The project includes designing a protective enclosure and testing the mat's reliability in real-world scenarios.

Deliverables: A functional visitor sensing mat prototype, circuit diagrams, and a short report on calibration and testing results.

Milestones

Submit a brief project plan outlining your approach, listing required components, and identifying potential challenges specific to piezo-based sensing for a welcome mat. Ensure your plan includes a timeline and initial sketches or diagrams of your intended system layout.

2. Sensor signal calibration

10 marks 6d

Collect raw signal data from your piezo sensor under various foot pressures. Document your calibration process, including threshold determination and noise filtering, and submit annotated plots showing how your system reliably distinguishes between visitor presence and background noise.

3. Trigger mechanism design

10 marks 6d

Design and implement a trigger mechanism that activates upon validated visitor detection. Submit circuit diagrams and code snippets, demonstrating how your system processes calibrated signals to reliably initiate a welcome response only when appropriate.

4. Output device interfacing

10 marks 6d

Interface your trigger mechanism with an output device (e.g., LED, buzzer, or display). Provide wiring diagrams, code, and a short video or photos showing your system successfully delivering a welcome signal when a visitor steps on the mat.

5. Enclosure design

10 marks 6d

Design and document a protective enclosure for your mat's electronics and piezo sensor. Submit CAD drawings or detailed sketches, specifying materials, dimensions, and assembly steps, ensuring the enclosure is robust, weather-resistant, and does not impede sensor function.

6. Prototype testing

10 marks 6d

Conduct prototype testing with multiple users and document results. Submit a test log detailing detection accuracy, false positives/negatives, and system responsiveness, along with a summary of any issues encountered and proposed improvements based on real-world use.
