If you are worried about monitoring CO2 but are always on the go you should check out this wearable. The ring changes color to give you an instant update. Picked up by Tom’s Hardware:

While precise details on the inner workings of the project have been kept under wraps, we can infer a few things from pictures provided so far. The ring is 3D-printed, features a CO2 sensor and uses an RP2040 to interpret sensor data and trigger LEDs on a NeoPixel ring.

If you want to check out this project up close, visit the original thread on Twitter and be sure to follow Guido Burger for more updates on this clever RP2040 CO2-detecting NeoPixel Ring.
