Air Quality Sensors | CO2 Sensors |

CO2 gas sensors are available in a number of ‘ppm detection ranges’. They utilize non-dispersive infrared (NDIR) to detect the presence of the gas. CO2 molecules absorb specific wavelengths of light and this is detected in the sensor. Heating and ventilation systems (HVAC) use these to provide demand controlled ventilation (DCV). Methane gas sensors are another example of air quality ...
