Abstract: A temperature compensation method for a weighing device, wherein the scale is provided with a temperature sensor, the method is performed by a processor, and includes, when the scale is powered on: 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. The present disclosure also provides a weighing device with temperature sensing function.
