It samples temperature, humidity, pressure, and a relative air-quality score every 10 seconds into SQLite, and serves a password-gated Flask dashboard over a Cloudflare named tunnel.</p> <p>The air-quality number is a relative 0 to 100 score, higher is cleaner. It is not a calibrated AQI. The gas sensor reads VOC resistance in ohms, which means nothing in isolation. The score compares the current reading against a rolling baseline of clean air in the same room, covered below.</p>
