Overview
Honeywell has designed the AQ Series with algorithmic compensation that gives users very high resolution and long-term stability.
These sensors are designed to be used in environmental applications with a variety of gases detected: Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Ozone (O3), Sulfur Dioxide (SO2).
AQ7 Series gas sensors are designed to be highly specific to the gas they are intended to measure, they will still respond to some degree to various other gases, achieving individual compensation for temperature and cross sensitivity.
