Project description:
"I have an ESP32-CAM wired to a pH sensor on a device and only a day left to turn the prototype into something I can demo. The must-haves are straightforward: stream the live camera feed, read the pH sensor, display both on a single page, and log everything with timestamps. Language is flexible—Arduino C++ or Python—so pick whichever lets us move quickest. Also, may pick between being a software or dashboard.

The main AI piece should look at the pH log and instantly suggest an action (“rinse”, “dose alkali”, etc.). A lightweight rule-based or ML approach is fine as long as it runs either on-board or in a tiny Python helper on my laptop. If there’s still time, I’d love pointers for adding obstacle detection or even a chat-style helper, but those are strictly nice-to-have.

Deliverables
• Commented firmware for ESP32-CAM that streams MJPEG and sends pH readings at the chosen sample rate
• Simple HTML/JS dashboard showing the live video, current pH value, and the latest AI recommendation with <2 s latency or may also include the robot's current battery condition
• Logging routine (CSV or JSON) saved to SD card or pushed to a local server—your call
• Compact AI script or on-device model that maps pH ranges (or patterns) to recommended actions
• Quick build-and-flash walkthrough so I can replicate the demo tomorrow

Acceptance criteria
• Web view loads, camera runs, pH updates live, and recommendations appear automatically
• Each sample is logged with timestamp, pH, and an optional image reference
• Code compiles and runs on readily available ESP32-CAM board definitions without modification

Just need a guidance when it comes to whats, wheres, and hows of all of this.

Guidance as well with the wirings and such. I only have like about 12 hours to work on this. Mode of payment paymaya or GCash around 15-18 dollars." (client-provided description)
