@AirmeterIO I'm interested, thx 3ivsm9l64@instancemail.net

Got a couple of bsky invite codes available. They will be given to the first followers who reply to this and can be contacted.

If interested in the particulars of this sensor see: senseair.com/products/power…

First tests with the newly released Sunlight CO2 sensor (dev & test units kindly provided by Senseair) look *really* encouraging! Image below shows three Sunlights and three Sunrises. This sensor brings the unit cost down significantly.

@wendyisacsson Managing 3 years is pretty impressive considering the environment in which you have to operate! Hope you recover swiftly.

I’ve done all I can for 3 years. Masked daily indoors, kept an eye on the CO2 level in my surroundings. But finally it got me too. Probably school- heartbroken and feeling really sick. Health tips without prescription in Sweden? Sources. High temp aches & pains exploding headache

@wendyisacsson @JimRosenthal4 @long_lawyer @johnwenger9 That also works ;)

@AirmeterIO @JimRosenthal4 @long_lawyer @johnwenger9 I was sitting in the aisle seat. Aranet was in my aisle pocket. I sat in the seat closest to the aisle. Full ventilation from all three overhead vents pointed at my face, dispersing exhaled air with turbulence all around me. I think the readings were pretty accurate!

The CO2 level on an aeroplane 2500-3700ppm. Picture 1 on the ground Picture 2 -2 flights takeoff/landing and 1 hour transfer! Flying doesn’t exactly feel like a safe way to travel- even with HEPA filters Should the CO2 level be this high? @AirmeterIO @JimRosenthal4 @long_lawyer

@wendyisacsson @JimRosenthal4 @long_lawyer 2) Preferably at least 1 meter away from the nearest human and not in the direct path of exhaled breath. Placing under seat in a (ventilated) pocket of a rucksack like @johnwenger9 did is about as ideal as one can get on a plane.

@wendyisacsson @JimRosenthal4 @long_lawyer That CO2 level could well be that high but it would be important to note: 1) At really high readings (5000+ definitely) accuracy will drop but you can be certain the readings are very high none the less. (1/2)

@johnwenger9 Where was the bag placed during the flight? Presumably it was left away from your person in bag for entire flight and readings data extracted later?

I put a CO2 monitor in the mesh pocket of my backpack during a short trip to #London last week. Thread on the observations: Note the traffic light colour scale: Green = CO2 below 1000 ppm Amber = C02 between 1000-1400 ppm Red = CO2 over 1400 ppm

Here is a preview of the new on device web portal built using @MaterialUI. Coming soon :)

@thomwink It's great to see Airmeter.io devices in real world tests :)

Higher values few minutes after additional passengers got in. Luckily I was able to get off the next station. Last reading in the corridor might be biased due to variation of temperature without equilibration.

Good impression so far with the beta device of @makehumantechn1 and @AirmeterIO A big thank you especially to @twtomcat for organising and assembling it!

AirMeter v0.2.1 is now available for download: github.com/airmeter-io/Ai…

Got to 2000+ ppm in real world danger zones (Irish pubs).

@CarlOGBengtsson One fix to the GPIO handling and it's looking a good bit better ;)

@AirmeterIO Thanks James, I understand better that it's power optimization of the "system" and not so much the CO2 sensor (yet) that you meant. You're on to something good (and cool) with this project. Keep it up! 👍🏻

Power optimization time :)

@CarlOGBengtsson Yep. Although the major blocker to "disconnected mode" has been solved for a while with the on device UI and buttons. Before this it needed to be online really to remain configurable. So these questions will become relevant :)

@CarlOGBengtsson Not to say their aren't improvements to be made to the connected scenario, hence bringing out the "power tools" again :) The EPD is being updated far more often than required for one.

@CarlOGBengtsson Once WiFI is disconnected for significant periods then much more aggressive deep/light sleep can be followed. This may bring Sunrise optimizations back into the picture :)
