ABSTRACT:
An object of the present invention is to provide a sensing device capable of easily grasping whether or not a concentration of a sensing target is equal to or less than a standard value.As a concrete means for solving the problem, a sensing device which senses, using a piezoelectric vibrator provided with an adsorbing layer for adsorbing a sensing target and electrodes, and having a natural frequency varied by an absorption of the sensing target, the sensing target by the variation of the natural frequency of the piezoelectric vibrator, is structured to include an oscillation circuit for oscillating the piezoelectric vibrator, a measuring section for measuring a concentration of the sensing target based on an oscillation output from the oscillation circuit, a storage section for storing data in which a plurality of sensing targets and their standard concentrations are corresponded to each other, a selecting unit for selecting the sensing target, a data processing section for reading out the standard concentration corresponding to the sensing target selected by the selecting unit from the storage section and comparing the standard concentration with a concentration detection value detected by the measuring section, and an output section for outputting a comparison result compared by the data processing section.
