ABSTRACT:
A low-cost fluid sensor which has a controlled resistance value is provided by depositing a resistance material between two electrodes on a portion of a molecular sieve layer. A heating resistor for drying out the fluid sensor may also be provided by depositing a resistance strip over another portion of the molecular sieve layer, or alternately by providing the resistance strip adjacent the molecular sieve layer on a supporting substrate.
