Why is humidity control so rare?
Total: 565, Categories: Hygrostat, Humidity display, Humidity control Evaporation (boiling): 4 Evaporation (natural): 17 Ultrasonic: 33 (but these are bad for asthmatics) Why do steam evaporators in particular hardly have any humidity measurement? Too much humidity causes mold, which is unhealthy again. A combined temperature and humidity sensor costs around 3, a mains power optocoupler around 8, both without bulk discounts. Are there any that are easily hackable so that you can retrofit them yourself?
