Adafruit SCD-30 - NDIR CO2 Temperature and Humidity Sensor

· The SCD-30 is an NDIR sensor (https:///CQ6), which is a '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 (https:///PF7) - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect ...

How does an NDIR CO2 Sensor Work? |

NDIR is an industry term for " nondispersive infrared ", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector.

On-Chip Non-Dispersive Infrared CO2 Sensor Based On an ...

Typically, NDIR CO2 sensors use the strong absorption of CO2 around m, a wavelength range where no other common molecules absorb, thereby avoiding cross-sensitivity issues. Due to these advantages, 83% of the European advanced CO2 sensor market uses NDIR sensors [4]. However, NDIR sensors tend to be bulky as a long (typically several cm) interaction length is required to …
