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

Fantastic and elegant looking nightstand or bathroom tray
Color: White 1 Pack, Size: 8" x 8" x 1.8"
I absolutely love this nightstand tray! The elegant gold trim gives it a luxurious look that instantly elevates my nightstand decor. It works perfectly as a perfume or cologne organizer and keeps all my bottles beautifully displayed. I’ve also used one as a dresser organizer countertop to hold jewelry and skincare, and another as a stylish key tray or key holder bowl by the front door. The quality is excellent and the design is both functional and beautiful. I love it so much, I’ll definitely be buying a few more to stack it up in a couple of my rooms. Highly recommend!
