FAQs - PM Sensor
Why measure PM2.5 and PM10?
Air that appears clear to the naked eye is not always clean. It may still contain a variety of harmful substances that are invisible to us. In addition to pollutants such as sulfur dioxide and nitrogen oxides, PM2.5 and PM10 are among the most critical. These fine particulate matters can carry toxic and hazardous substances, remain suspended in the atmosphere for extended periods, and pose serious threats to human health.
Recognizing their impact, the World Health Organization (WHO), the U.S. Environmental Protection Agency (EPA), and environmental authorities worldwide have designated PM2.5 and PM10 as key regulated pollutants. Real-time monitoring of these particulates is essential for effective urban air quality management and ensuring compliance with environmental standards.
What is an air quality sensor?
The air quality sensor is a device that detects the concentration of particulate matter in the air and can be used in indoor or outdoor environments.
How does the air quality sensor work?
The laser scattering measurement principle is used to measure the concentration of particulate matter in the air.
What does this air quality sensor measure?
Our air quality sensor is mainly used to measure PM2.5, PM1.0 and PM10 in the air. If you need to measure other pollutants, you can choose our multifunctional air quality sensor.
Where can I find out more information?
