Weighing device with temperature sensing function and temperature compensation method thereof

A weighing device with temperature sensing function, comprising:

• a scale having a weighing surface, and a subject being carried by the scale selectively;
• a temperature sensor positioned on the weighing surface of the scale or positioned within the scale and located at a surrounding of a position, and the subject being sensed by the temperature sensor selectively;
• and
• a processor connected to the scale and the temperature sensor and disposed internally or externally to the scale, wherein when the scale is powered on, the processor performs:
• receiving a first ambient temperature from the temperature sensor at a first time point;
• receiving a second ambient temperature from the temperature sensor at a second time point;
• obtaining a first compensation value associated to a default temperature threshold and a relationship between the first ambient temperature and the second ambient temperature, and obtaining a cumulative compensation value updated by the default temperature threshold;
• and
• obtaining a calibrated target temperature that is a target temperature of a subject sensed by the temperature sensor being calibrated by the cumulative compensation value;
• wherein the first time point is earlier than the second time point.
