Ikea VINDRIKTNING Air quality sensor HOW IT WORKS

Another interesting device from IKEA, this is Ikea VINDRIKTNING Air quality sensor
Let's see how it works and what is inside.

i'm a bit late, but the infrared led could be a ambiant light sensor, i have the same model at home, and the brightness of the leds adjust automatically to the brighness of the room. not sur why your unit wasn't doing it tho

[@InsideOutElectronics]

Certainly, i just could not locate the sensor during my teardown !

[@user-yq8ue7mr9i]

I always wondering how the brightness of the indicator change. Thanks for your tear down, that infrared sensors work just as the light sensor in our phone, but it won’t change for your room light but the sun light!
You can hit that sensor with a remoter to see it change brightness

I didn't know it was an infrared sensor until he mentioned it. Indeed the brightness of the AQ sensor starts flickering with the IR TV remote :D

6:14 Air quality numbers are in μg/m³. So 0-35 means 0 μg/m³ - 35 μg/m³

Thank you! This is useful !

tnx

[@InsideOutElectronics]

Thank you for wathing

Hack it 👍 it's already been connected to esp32 by others...

[@InsideOutElectronics]

Thank you for feedback, I will. I saw actually quite few different solutions !

Hahahahahahhahaha! Cannot blame you for you may not be familiar how that really works. I was yelling in my head "WHY!". HAHAHAHAHAHAHAH! I thought you knew how it works since you are into electronics and it is an electronics part.
1) The said "soot" is not soot. It is vaporised wax. It settles on surfaces, hence the sensor is fundamentally stuck with solidified/condensed wax. The sensor could have been permanently blocked with that wax. Vaporised wax is rather heavy, it cannot stay suspended in the air for that long relative to that smoke from a match.
2) That LED thing makes up the opto-sensor thing identical to that in mouse and in anything which needs counting. It is also used to measure bacterial growth or spores by optical density.

Thank you for watching, this video about how the whole unit works not about how PMS works.
Also when candle burns it should not emit any wax vapor, - only water, co2 and small amount of soot. You are welcome

You are wrong again.
