The ATO Air Quality Monitor is a versatile and reliable device designed to provide real-time air quality data. It is capable of detecting a wide range of pollutants, including formaldehyde (HCHO), total volatile organic compounds (TVOC), particulate matter (PM2.5, PM1.0, PM10), carbon dioxide (CO2), temperature, and humidity.

This monitor utilizes advanced sensor technology to ensure accurate measurements. For instance, it employs a high-sensitivity electrochemical sensor for formaldehyde detection and a high-precision laser sensor for PM2.5. The device also features an infrared sensor for CO2 measurement. With a sampling frequency of 1.5 seconds, it provides constantly updated readings.

The monitor is equipped with a digital LCD display that clearly shows the levels of various pollutants. It also has an alarm function that alerts users when pollutant levels exceed safe thresholds. The device is compact, lightweight, and easy to use, making it suitable for home, office, or car use. It is powered by a rechargeable lithium battery and can be charged via a micro USB port.

To ensure accurate results, the monitor should be calibrated outdoors before initial use. It is also important to avoid covering the air intake areas and to keep the device away from strong winds, chemicals, and liquids.
