Airvalent CO2 monitors.

Exciting to see how small these are getting, similar size to apple airpods case. Looking forward to seeing this tech ~1-3 versions from now, where air quality monitoring can just be part of a smartwatch.

Just as expensive as aranet 4 though, looking forward to seeing this tech getting cheaper 😄

aranet 4 probs the most useless thing i ever bought 😭

basically tells you when to open a window, which your brain already does naturally

for me, when i confirmed that was the signal the brain gave me, the device lost most of its meaning

Oh, I thought co2 was hard to detect and people have gotten sick from having it in thier homes which made these important…

its possible thats scientifically correct, but to get co2 poisoning you need extreme levels of bad air afaik

i think most ppl in tech use them to be aware of "stuffy" air, which mostly makes you a bit dull (and the cure for that is to open a window)
