A dust sensor typically works by shining a light source through the air and measuring the amount of light that is scattered by particles in the air. The sensor detects the intensity of scattered light to estimate the concentration of particles in the air, which is then translated into a measurement of dust levels.

No, a hygrometer measures the humidity in the air, not the amount of dust. Dust particles in the air can be measured using a particulate matter sensor or a dust monitor.

Charcoal dust works by adsorbing toxins and impurities onto its porous surface, allowing it to trap and remove them from the environment or a substance. This makes charcoal dust commonly used in air and water purification systems, as well as in skincare products to help draw out impurities from the skin.
Because the dust bowl is the SOURCE of the dust raised by a dust storm.
There are three main categories of dust: inorganic dust (such as mineral dust and metal dust), organic dust (such as dust from plants and animals), and synthetic dust (such as dust from construction materials and chemicals). Each category can contain various types of dust particles with different compositions and properties.
