[Introduction]:This module is widely used in air purifiers, fresh air ventilation systems, intelligent integrated ceilings, air quality monitors, ventilation fans, air conditioners, etc. It is mainly used for the detection of air quality. It has high sensitivity for various low-concentration pollutants in the air, such as cigarettes, odors from cooking, TVOC (gas volatile from organic solvents), etc. This uses advanced gas sensors and scientific software processing to achieve control closer to human senses and to detect the level of air pollution.
