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: https://t.co/0HLLT785yq

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.

[AirMeter.io @AirmeterIO]

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

[AirMeter.io @AirmeterIO]

@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.

[AirMeter.io @AirmeterIO]

@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?

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

@thomwink It's great to see https://t.co/KeeWkmkhAj devices in real world tests :)

[AirMeter.io @AirmeterIO]

AirMeter v0.2.1 is now available for download: https://t.co/q9GIiVbyfK

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 ;)

[AirMeter.io @AirmeterIO]

Power optimization time :)

[AirMeter.io @AirmeterIO]

@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 :)

[AirMeter.io @AirmeterIO]

@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.

[AirMeter.io @AirmeterIO]

@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 :)
