NOX sensor
An oxides of nitrogen sensor is used to monitor the levels of oxides of nitrogen that a vehicle emits to ensure it is compliant with emissions regulations.
Oxides of nitrogen (otherwise known as NOx) are pollutants that have both environmental and health impacts. NOx usually refers to nitric oxide (NO) which becomes nitrogen dioxide (NO2) when it combines with oxygen under high temperatures. This reddish-brown gas makes summer smog look brown and hazy in high-traffic areas.
The gases are poisonous and highly reactive. They can affect and contribute to respiratory infections and asthma, especially in children, as well as cause detrimental effects to local ecosystems and road visibility.
Controlling the levels of NOx emitted into the atmosphere is incredibly important, which makes the NOx sensor a vital vehicle component.
