ESP32 Fingerprint Web App Enclosure

Summary

Build a biometric security system with this 3D-printed enclosure for an ESP32 and fingerprint sensor (e.g., R307)! This project features a web-based interface to enroll, verify, and list fingerprints, accessible via WiFi on any browser. The included STL files create a sleek, protective housing for your ESP32 and sensor. Perfect for IoT enthusiasts and makers exploring biometric applications!

Hardware Needed:

• ESP32 (e.g., ESP32-WROOM-32)
• Fingerprint Sensor (Adafruit-compatible, e.g., R307)
• USB Cable
• 3D Printer (for STL files)

Connections:

• RX (sensor) → GPIO 16
• TX (sensor) → GPIO 17
• VCC → 3.3V/5V
• GND → GND

3D Printing:

• Use PLA/PETG, 0.2mm layer height, 20% infill, supports as needed.
• Ensure access to sensor window and USB port.

Code & Setup:

• Full Arduino code, images, and instructions: GitHub Repository
• Install Adafruit_Fingerprint library, update WiFi credentials, and upload to ESP32.
• Access the web app (login shown below) via the ESP32’s IP address.
