Just waiting for the followup post on HN: How I sent CO2 warnings to my entire office using an ESP32
replyWhat if a movie theater puts an Apple CO2 meter next to an air inlet? Everybody will think the air is safe.
replyIf that’s the sole source and the application does thoughtful analysis it could determine that there are sections of the room that are better than others, yes
replyBut realistically, using what sensors?
replyAnd (maybe less realistically) what if the theater puts 5 Apple sensors inside a sealed CO2-free chamber, spread around the room?
That’s the point of this thread that each device would have a small sensor that would sync and aggregate with others in the room
replyI think the thread established that CO2 sensors are too bulky for that.
replySo were most other sensors before Apple (and their suppliers) miniaturised the sensors. Gps and imu was huge in the 90s, several pound each.
