Relative Humidity Sensor Enclosed With Ceramic Heater.

摘要

Sensor systems and methods are disclosed herein. A relative humidity sensor can be associated with one or more ceramic heating elements configured from a porous material. In general, a perimeter of the relative humidity sensor is surrounded with a relatively conductive material. A resistive material surrounds one or more of the ceramic heating elements, such that air that is saturated with water vapor passes through the porous material of the ceramic heating element(s). Water vapor can therefore be heated by the ceramic heating element(s) in order to evaporate water droplets associated with the water vapor and thereby reduce relative humidity to a measurable level. The porous material of the ceramic heating element(s) can be provided via a plurality of laser drilled holes to create such porosity.
