1. A temperature compensation method for a weighing device, wherein the weighing device comprises a scale, a temperature sensor and a processor, the temperature sensor is positioned on a weighing surface of the scale or positioned within the scale, the processor is disposed internally or externally to the scale, and the method is performed by the processor and comprises:
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.
