What are the different types of air quality sensors?

What are the different types of air quality sensors?

There are several types of air quality sensors, including chemical sensors, optical sensors, and electrochemical sensors. Each type measures different pollutants.

Can you explain how electrochemical sensors work?

Electrochemical sensors work by detecting specific gases through a chemical reaction that produces an electrical signal proportional to the gas concentration.

What pollutants can optical sensors detect?

Optical sensors can detect pollutants like particulate matter (PM), volatile organic compounds (VOCs), and gases such as carbon dioxide and ozone.

Which type of sensor is best for indoor air quality?

For indoor air quality, electrochemical sensors are often preferred due to their sensitivity to common indoor pollutants like carbon monoxide and formaldehyde.

Are there any sensors that can measure multiple pollutants?

Yes, some advanced sensors can measure multiple pollutants simultaneously, providing a comprehensive overview of air quality.
