ESP-AirSense SCD30
Indoor air monitor built on ESP32-WROOM-32, 1.8″ TFT 128×160 SPI (ST7735), and Sensirion SCD30 (NDIR). The SCD30 measures CO₂ in 0–40,000 ppm (typical calibrated band 400–10,000 ppm). Firmware samples every 2–10 s, applies ABC (Automatic Baseline Correction) and supports manual offset calibration (e.g., outdoor ~400 ppm) so you can set a “healthy” target (commonly ≤800 ppm) and derive clear ventilation guidance.
On-device UI shows large CO₂ (ppm) and a color status:
- < 800 ppm: Good (green)
- 800–1000 ppm: Caution (yellow)
- 1000–1400 ppm: Ventilate (orange)
- > 1400 ppm: Stagnant / high risk (red)
