Assignee: LG ELECTRONICS INC.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 30:
31. The method of claim 29, further comprising:
when the radio signal is determined to be the signal requesting measurement of salinity,
supplying driving voltage to the first electrode and the second electrode to sense a third measurement voltage corresponding to the impedance change of the first electrode and the second electrode to which the sensing target material is brought into contact with;
determining whether a predetermined time has passed after the driving voltage is supplied;
receiving the third measurement voltage sensed at the first electrode and the second electrode when the predetermined time has passed;
determining whether the first sampling voltage obtained by sampling the third measurement voltage according to a set sampling cycle falls within either a range of a set first sampling voltage value or a range of a second sampling voltage value greater than the first sampling voltage value; and
when the first sampling voltage falls within the range of the second sampling voltage value, generating a fourth digital signal corresponding to salinity calculated by applying the first sampling voltage to a set primary single equation so as to transmit the fourth digital signal to the external device.
