IKEA made a smart air quality sensor to track indoor pollution
I have extensively tested the previous model and it was a bit of a mixed result with the strongest selling point the price being really affordable. You can see my review and test result on our blog [1].<p>One of the biggest negative points that I found was that the traffic light cut off points are way off. So it shows a green light from 0-35 μg/m³ whereas the WHO defines the annual limit now at less than 5 μg/m³.<p>Unfortunately in this new model this seems still to be the case and has not been improved (according to the manual [2]). So the VINDSTYRKA still gives misleading indications through the traffic light but at least you can now see the μg/m³ on the display and make a more informed judgement (compared to the old model without display).<p>It is difficult to make a judgement on the accuracy without really running it through a test cycle but it is definitely missing a CO2 sensor. Measuring CO2 indoors is most likely the most important parameter, especially if you live outside strongly polluted areas e.g. in Asia.<p>CO2 sensors that give good accuracy are relatively expensive and I believe it was probably shelved because of costs which is a pity. So this looks like a big missed opportunity but I will try and source one of these and write a review.<p>If you are interested for a DIY kit with high quality sensors, check out our AirGradient kits [3].<p>[1] <a href="https://www.airgradient.com/open-airgradient/blog/ikea-vindriktning-accuracy" rel="nofollow">https://www.airgradient.com/open-airgradient/blog/ikea-vindr...</a><p>[2] <a href="https://www.ikea.com/cz/cs/manuals/vindstyrka-senzor-kvality-vzduchu-chytre__AA-2351596-1-2.pdf" rel="nofollow">https://www.ikea.com/cz/cs/manuals/vindstyrka-senzor-kvality...</a><p>[3] <a href="https://www.airgradient.com/open-airgradient/kits/" rel="nofollow">https://www.airgradient.com/open-airgradient/kits/</a>
