Visual IAQ Indicators for Instant Understanding

Traffic Light Status Indicator

Uses color-coded signals to quickly show air quality levels for instant adjustment.

  • Green Excellent air quality
  • Yellow Moderate conditions
  • Red Poor air quality

Emoticon Indication(AM103 Only)

Provides intuitive emotional feedback to help users understand indoor air conditions in a more human-friendly way.

  • Green Excellent
  • Yellow Normal
  • Red Poor

Enhanced Data Display (AM103 Only)

Key metrics are highlighted in larger, clearer fonts for readability, including CO2 trends, humidity, status icons, and last update time for intuitive on-site monitoring.

Energy-Saving Modes for Extended Battery Life

Smart Screen Mode

Reduces display refresh when readings remain stable, helping save power while maintaining continuous sensing and data transmission.

Note: Screen refresh is triggered only when values change beyond defined thresholds or at configured intervals.

Hibernation Mode

Designed for extended idle periods, significantly reduces power consumption by disabling data collection while keeping the device in a low-power state.

Note: Hibernation consumes less power than Smart Screen Mode due to disabled data collection.
