Arduino | Adafruit SCD-30 - NDIR CO2 Temperature and Humidity Sensor …

09/07/2021· The SCD-30 is an NDIR sensor, 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 - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific experiments, …

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. The IR light detector measures the amount of IR light that ...

CO2 Sensor for Schools : 6 Steps (with Pictures) - Instructables

So CO2 will build up in a room with poor ventilation, just as COVID-containing aerosols will. With schools, and other places of business, returning to in-person activities, it is challenging to know the air quality in a room. CO2 sensors are a pretty good way to indicate how dense the amount of previously-respired air in a space is, and therefore how much potential COVID could be in the air. There are …
