ABSTRACT:
A humidity sensor system and method include a ceramic substrate upon which a heater can be printed. A humidity sensor can be mounted above and in contact with the heater, or the heater can be mounted one side of the substrate and the humidity sensor on the opposite side of the substrate, such that the heater heats the humidity sensor, raising its temperature above the dew point of the ambient air such that moisture does not condense on the humidity sensor, thereby preventing the humidity sensor performance from being affected. The heater can be configured as a resistive heater, and the humidity sensor can be configured from one or more humidity-sensing die. A thin film platinum RTD (Resistance Temperature Detector) component can be printed upon the substrate in association with the humidity sensor.
