According to a website that shows the levels of fine dust or ultrafine dust, there was also a NO2 value, a nitrogen oxide, for air pollution.
How can I measure nitrogen oxides?
Is there a simple measurement method or measuring machine like fine dust?

Nitrogen oxide was at the car inspection station.
I think it will be difficult for the general public to use like a fine dust meter.
There is an automatic measuring instrument that measures the concentration of nitrogen oxides.
Usually, the exhaust gas measurement in the automobile inspection station is measured by chemical emission method, infrared absorption method, ultraviolet absorption method, electrostatic potential electrolysis method, and electrostatic potential method.
Nitrogen oxides in the atmosphere are measured using absorbance photometry and chemiluminescence methods.
It's not easy to measure in a typical home.
