MEASUREMENT DEVICE
First Claim
1. A measurement device adapted for use with a current-type sensor unit, which, when applied with a driving voltage, is capable of reacting with a target substance for generating a sensor current that corresponds to a concentration level of the target substance, said measurement device comprising:
- a driving unit operable to generate the driving voltage that includes an alternating current (AC) component and a direct current (DC) component, and adapted to be connected electrically to the current-type sensor unit for providing the driving voltage to the current-type sensor unit; and
a processing unit adapted to be connected electrically to the current-type sensor unit for receiving the sensor current from the current-type sensor unit, and operable to determine the concentration level of the target substance according to a peak-to-peak value of the sensor current received by said processing unit.
