Milerd air quality analyzer work by using advanced sensors to detect and measure various air pollutants. These sensors can detect particulate matter (PM2.5 and PM10), volatile organic compounds (VOCs), carbon monoxide, and other harmful gases. The data collected is then processed and displayed on the device or a connected mobile app, providing real-time information about air quality levels. If pollutant levels exceed safe thresholds, the monitor issues alerts, allowing users to take immediate action to improve indoor air quality.
