2021-08-14· Adafruit SCD-41 – NDIR CO2 Temperature and Humidity Sensor – STEMMA QT / Qwiic. The SCD-41 is a photoacoustic ‘true’ CO2 sensor that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn’t approximating it from VOC gas concentration – it really is measuring the CO2 concentration! That means it’s bigger and more …

Carbon dioxide sensor - Wikipedia

A carbon dioxide sensor or CO 2 sensor is an instrument for the measurement of carbon dioxide gas. The most common principles for CO 2 sensors are infrared gas sensors and chemical gas sensors. Measuring carbon dioxide is important in monitoring indoor air quality, the function of the lungs in the form of a capnograph device, and many industrial processes. Nondispersive Infrared (NDIR) CO 2 ...

Basic Principle of NDIR Gas Detection - Heimann Sensor

The picture below illustrates the principle using the example of a NDIR CO2 sensor: On the right side we have an IR light source that emits radiation at all wavelengths. The reflector is used to direct as much light as possible in the direction of the thermopile detector which is on the left side. In between there is a tube with IR reflecting walls which is used as measurement path. For CO2 ...
