What Hacker News says?
The article already mentions connecting a Wemos D1 mini, which lead me to searching for a howto. Stumbled onto this excellent article by my old friend Guy, complete with assembly pictures: https://style.oversubstance.net/2021/08/diy-use-an-ikea-vind...

on “Ikea Vindriktning Air Quality Sensor Review and Accuracy”For folks who want to do something similar (no CO2 measure, and possibly less accurate) for far less per sensor, you can easily connect an ESP8266 ($5) to an IKEA VINDRIKTNING ($16) air quality sensor[1]. Stick a AM2302 ($7) on the outside and you get PM2.5, temperature and humidity for about $30. [1]: https://style.oversubstance.net/2021/08/diy-use-an-ikea-vind...

on “IKEA launches VINDSTYRKA – a smart sensor to measure indoor air quality”IKEA hack https://style.oversubstance.net/2021/08/diy-use-an-ikea-vind... and of course previously on HN, airgradient DIY https://news.ycombinator.com/item?id=27124671 The more the better. Maybe one day built into every smoke detector. Maybe in a decade built into your phone. Another decade in your watch.
