Air quality meter / sensor

VINDSTYRKA IKEA air quality sensor. Bought 2 months ago from IKEA to understand why I don't understand the climate of my new apartment. Now I know that humidity will be my daily ally, and for this task, a dehumidifier was purchased, which also takes measurements. So this little wellbeing friend is no longer needed. Let it help someone else. Box is not preserved. Located in Āgenskalns. Shipping with Omniva (extra charge).
