Ikea Vindriktning Air Quality Sensor Review and Accuracy
Author here. I forgot to mention:With a Wemos D1 mini (ESP8266) MCU that costs around USD 2.00, you can pretty easily make the Vindriktning WiFi connected and get the data to a backend [1].You just need to solder three wires, and there is enough space within the enclosure to fit the D1 mini inside.This would then allow you to get the exact measurements and to better understand if the "green" is more on the lower end or the higher side.[1] https://github.com/Hypfer/esp8266-vindriktning-particle-sens...
