Tips: What is a PM sensor?

A PM sensor, or particulate matter sensor, is a device designed to measure and monitor the concentration of airborne particulate matter in the atmosphere. Particulate matter refers to tiny particles or droplets in the air that can vary in size, composition, and origin. These particles can have diverse sources, including industrial emissions, vehicle exhaust, construction activities, and natural sources like dust and pollen.

PM sensors are crucial tools in environmental monitoring and air quality management. They typically utilize various technologies such as laser-based scattering, light absorption, or gravimetric methods to quantify particulate matter concentrations. The results are often reported in terms of particle size fractions, with PM2.5 (particles with a diameter of 2.5 micrometers or smaller) and PM10 (particles with a diameter of 10 micrometers or smaller) being common metrics.

As air pollution poses significant health risks, including respiratory and cardiovascular problems, PM sensors play a pivotal role in assessing the quality of the air we breathe. Real-time data from these sensors can inform public health decisions, guide regulatory measures, and empower individuals to take actions to minimize exposure to harmful airborne particulates.
