Abstract
An antioxidant sensor includes a pressure sensor configured to obtain a contact pressure between an object and an optical sensor; the optical sensor configured to, based on the obtained contact pressure exceeding a set threshold pressure, emit a first light of a first wavelength to the object, and receive the first light reflected or scattered from the object; and a processor configured to determine a contact portion of the object in contact with the optical sensor, set a threshold pressure, among different threshold pressures, according to the determined contact portion, and determine an antioxidant value based on the received first light.
Claims22
An antioxidant sensor comprising:
- a pressure sensor configured to obtain a contact pressure between an object and an optical sensor;
- a processor configured to:
- set a first threshold pressure and a plurality of second threshold pressures;
- determine whether the object is in contact with the optical sensor based on the obtained contact pressure exceeding the first threshold pressure, and determine a contact portion of the object in contact with the optical sensor;
- and
- select a second threshold pressure, among the plurality of second threshold pressures, according to the determined contact portion, wherein the plurality of second threshold pressures respectively correspond to different contact portions, and
- the optical sensor configured to, based on the obtained contact pressure exceeding a set the selected second threshold pressure, emit a first light of a first wavelength to the object, and to receive the first light reflected or scattered from the object,
- wherein the processor is configured to determine an antioxidant value based on the received first light.
A method of obtaining an antioxidant value, the method comprising:
- obtaining a contact pressure between an object and an optical sensor;
