5. Operating Instructions
5.1 Understanding the Display
The clear display provides real-time readings for:
- PM2.5: Particulate matter concentration.
- AQI: Air Quality Index, derived from PM2.5 levels.
- Temperature: Ambient temperature in Celsius or Fahrenheit.
- Humidity: Relative humidity percentage.
5.2 Operating Modes
The S1-UP features two operating modes to optimize battery life and monitoring frequency:
- Smart Mode (Automatic): Provides continuous monitoring with a battery life of approximately 20 days.
- Power-Saving Mode (ECO): Takes readings every 30 minutes, extending battery life to approximately 60 days.
To switch between modes, short press the Mode button. The current mode will be indicated on the display.

5.3 Continuous Real-time Monitoring
For continuous 1-second real-time monitoring, it is recommended to keep the device plugged into a power source and set it to Smart Mode. This ensures the most precise and timely air quality data.
5.4 Switching Temperature Units
To switch between Celsius (°C) and Fahrenheit (°F) temperature units, long press the Mode button.
5.5 Air Quality Alerts
The device provides visual alerts through its indicator bar and AQI readings, categorizing air quality into different levels:
- Good: PM2.5 (0-12 µg/m³), AQI (0-50)
- Average: PM2.5 (12.1-55.4 µg/m³), AQI (51-150)
- Unhealthy: PM2.5 (>55.4 µg/m³), AQI (>150)

6. Maintenance
6.1 Cleaning
Gently wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the casing or internal components. Ensure the air inlet/outlet vents are free from dust accumulation.
6.2 Battery Care
To prolong battery life, avoid fully discharging the device frequently. If storing the device for an extended period, charge it to approximately 50% and store it in a cool, dry place.
7. Troubleshooting
- Device not turning on: Ensure the device is charged. Connect it to a power source using the Type-C cable and try again.
- Inaccurate readings: Ensure the device is placed in an area with good air circulation, away from direct drafts, heat sources, or strong odors. Allow a few minutes for readings to stabilize after powering on or moving the device.
- Display not working: If the display is blank or frozen, try restarting the device by holding the power button. If the issue persists, contact customer support.
- Short battery life: Ensure the device is fully charged. Consider switching to Power-Saving (ECO) mode if extended battery life is preferred over continuous real-time monitoring.
