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

I love how easy this children’s dental floss is. My child with ASD is able to use with little to no help. it’s been years trying to get my child with sensory sensitivities to floss or brush teeth without a HUGE STRUGGLE, however this is very gentle and something that makes our oral health care routine smoother. ( if you know, you know!!) It is very similar to the viral “ usmile” adult version water flossers. My only complaint/issue with this is that it collapse pretty easily and sometimes it’s hard to keep in the locked position while flossing teeth. Overall a good product, and recommend.?

Good for kids

Color: Blue+red

A little powerful for my 8 year old at first but after he got the hang of it, he loves using it.

Great for dental appliances

Color: Pink+purple

My daughter has a dental appliance that can get food caught in it. We were told to try a water flosser to get the trapped food out. This has done exactly that. Very happy with it.
