How Air Quality Monitors Work: The Science Behind the Technology
Air quality monitors are devices that measure the quality of the air in a particular area. They have become increasingly popular in recent years, as people have become more aware of the negative effects of poor air quality on health and well-being. But how do air quality monitors work? In this article, we will explore the science behind the technology. Sensor Technology The most important component of an air quality monitor is its sensor. The sensor detects various pollutants in the air, such as particulate matter, carbon monoxide, and volatile organic compounds. The type of sensor used depends on the specific pollutants being measured. Optical Sensors Optical sensors are used to detect particulate matter in the air. They work by shining a light source through a sample of air and measuring how much of the light is absorbed or scattered by the particulate matter. The amount of light that is absorbed or scattered can be used to determine the concentration of particulate matter in the ai
