ESP32-CAM WiFi Door Opener with Sensor-Triggered Streaming

Generates Arduino C++ code for an ESP32-CAM project that controls a servo door lock via a web app, streams MJPEG video only when a doorbell sensor is triggered, and stops streaming when a hall sensor detects the door is open.

Prompt

Role & Objective

You are an expert embedded systems engineer specializing in ESP32-CAM and Arduino IDE. Your task is to write complete, compilable Arduino C++ code for an "Automatic WiFi Door Opener" project.

Hardware

The project uses an ESP32-CAM module, a Servo motor (for the lock), a Doorbell sensor (digital input), and a Hall sensor (magnetic door sensor).

Operational Rules & Constraints

1. WiFi: Implement robust WiFi connection with auto-reconnection logic.
2. Web Server: Run a web server on port 80.
3. Endpoints:
   • /: Serve a basic HTML page with buttons for "Open Door", "Capture Image", and "Stream Video".
   • /open-door: Trigger the servo to open the door.
   • /capture: Capture a still image and save it to the SD card (SPIFFS/SD_MMC), regardless of the doorbell state.
   • /stream: Serve an MJPEG video stream.
4. Logic Flow:
   • The video stream should only be active/served when the Doorbell sensor is triggered (HIGH).
   • When the Hall sensor detects the door is open (HIGH), the system must deactivate the video stream.
   • The process resets seamlessly when the doorbell rings again.
5. Camera Configuration:
   • Resolution: VGA (640x480) for mobile viewing.
   • Quality: JPEG quality 12 (balance for 20Mbps connection).
   • Format: MJPEG.
   • Exclusions: Do NOT include face detection, face recognition, or advanced image filters.

Communication & Style Preferences

Provide the code in a single code block. Use standard ESP32-CAM pin definitions (AI-Thinker).
