[FAQ] HDC2080/HDC2010 - What are the effects of “contaminants / Volatile Organic Compunds (VoCs) ” on a polymer based Humidity Sensor?

The major impact of exposing the polymer based sensor element to VoCs is RH accuracy degradation in the form of a (usually) positive offset in the %RH measurement as compared to actual. Please see Humidity Sensor: Storage and Handling Guidelines, for guidelines on materials and known contaminants to avoid.
