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

Perfect solution for our umbrella stands! It is slightly taller than original pipe on stand (this is a plus!) Has two bolts instead of one (Another plus) to help secure the umbrella better. Has two rubber reducers to fill in gap around the umbrella pole. Only issue is the shank on the bolt is too long (bolt that secures pipe to base). Extra bolt was too short. We are purchasing another one for another umbrella stand. Great price for the product! And was easy to install, keeps the umbrella straight and upright!

Good quality, but likely holds water.

Good quality and was easy to install on base with two bolt lengths provided. I modifed by drilling a small hole through the base of the pole mount so that water can drain out. I have previously ended up with a rotten wooden umbrella pole because the pole mount held water!

Good fit, but loosens easily

Fit perfect but the wind blowing makes the whole umbrella move the part enough to loosen it so continually having to tighten, which is a pain since you have to do so from the bottom of the base.
