Adafruit SCD-41 - True CO2 Temperature and Humidity Sensor - STEMMA QT / QwiicThe SCD 41 is a photoacoustic "true" CO2 sensor designed to measure the CO2 concentration (in parts per million, PPM) in ambient air. Unlike sensors like the SGP30, which approximate CO2 levels based on VOC gas concentration, the SCD 41 directly measures CO2, making it highly accurate but also larger and more expensive. It is ideal for environmental sensing, scientific experiments, and air quality studies. This sensor uses a different measurement

Reliable part
The price of this item was a bit of a shock. A good one though. I gave it to my mechanic, he installed it with no problems. Runs just fine. Would buy again
