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

The nine-inch oak shelf is well made, and is 45 degrees. The wall where I planned to install it was not, and I suspect this is the problem some of the reviews saying the shelf was not made at 45 degrees. In my case, we removed wood a bit at a time until we achieved a good fit. We did receive all of the hardware, but beware. The plastic straight insert anchors do not snug up with the supplied screws. However we used the supplied plastic toggles with better results. The hardware is why I rate this 4 stars. Otherwise, it is a nice piece, and well worth the price.
