Temperature Measurement Correction Using Multiple Temperature Sensors

摘要

Correcting a temperature measurement of a target sensed at one temperature sensor in an asset tracking device by using another temperature sensor. The asset tracking device includes at least one heat source that affects the temperature sensor for sensing the temperature of the target. The other temperature sensor measures temperature at a location in the asset tracking device. The relationships between an actual temperature of the target and the temperature measured at the two sensors are established through experiments or model. Using the relationships, the measured temperature of the target can be corrected to obtain a corrected temperature of the target.
