1. A bio-sensing device capable of automatically detecting a sensing code, the bio-sensing device comprising:

  • a bio-sensing strip comprising;

    a first electrode being electrically connectible to an electronic circuit and having enzyme contained therein to react with a sample;

    a second electrode being electrically connectible to the electronic circuit and having the enzyme contained therein to react with the sample;

    a passive component having an end thereof connected to the first electrode and having a physical value that is able to represent a sensing code of the bio-sensing strip; and

    a third electrode being connected to the other end of the passive component so that the passive component is able to be electrically connected to the electronic circuit; and

    a process-and-display unit being configured to quantitate an electrochemical reaction signal representing an electrochemical reaction of the sample with the enzyme contained reagent matrix, the process-and-display unit comprising;

    a detection circuit being electrically connectible to the bio-sensing strip to detect the physical value of the passive component and configured to convert the physical value into a first digital signal;

    a read circuit being electrically connectible to the bio-sensing strip to read the electrochemical reaction signal representing the electrochemical reaction of the sample with the enzyme contained reagent matrix and configured to convert the electrochemical reaction signal into a second digital signal;

    a microprocessor being electrically connected to the detection circuit and the read circuit and configured to verify the sensing code of the bio-sensing strip by processing the first digital signal and further set an appropriate compensation value, configured to receive the second digital signal and process the second digital signal into a sample measurement value, and configured to numerically compensate the sample measurement value based on the appropriate compensation value to output an accurate sample magnitude value; and

    a display member being electrically connected to the microprocessor to display the accurate sample magnitude value.
