AQI Alarm Function
The device provides visual and audible alerts based on the Air Quality Index (AQI) levels. The AQI is categorized into three stages:
- Mode normal: AQI 0-50 (Green indicator)
- Mode d'avís: AQI 51-100 (Yellow indicator)
- Danger Mode: AQI 101-500 (Red indicator)
When the AQI index exceeds 100 (Danger Mode), the device will emit an audible alarm. To stop the alarm sound, press the "UP" button (marked with '+').
