Consider this as a health watchdog, never sleeping. These sensors can detect tiny particles known as PM2.5 that escape the filtration of your nose and become embedded deep within your lungs. How does an air quality sensor function? Most devices rely on laser technology to count microscopic bits floating in the air. Particles that stream through a laser beam scatter light. This scattered light is detected by a sensor used to calculate pollution.
