Abstract
A sensing device is to be connected to a piezoelectric resonator for sensing a target substance in a sample fluid based on oscillation frequency of the piezoelectric resonator. The sensing device includes an oscillator circuit, a voltage supply unit, an information obtaining unit, and a voltage adjusting unit. The oscillator circuit is commonalized for a plurality kinds of piezoelectric resonators. The voltage supply unit is configured to supply a DC drive voltage to the oscillator circuit. The information obtaining unit is configured to obtain type information of a piezoelectric resonator which is connected to the oscillator circuit. The voltage adjusting unit is configured to adjust the DC drive voltage to a voltage corresponding to the connected piezoelectric resonator based on the type information obtained by the information obtaining unit.
