| 摘要 |
An arrangement for estimation of ambient temperature of an electronic device is disclosed. The electronic device comprises a power consuming unit, which is subject to self heating when in use. The arrangement comprises at least a first and a second temperature sensor and a processor. The sensors are adapted to produce first and second temperature measurements as functions of time respectively, and a temperature transport time to the first sensor from the power consuming unit differs from a temperature transport time to the second sensor from the power consuming unit. The processor is adapted to determine an ambient temperature estimate based at least on the first and second temperature measurements as functions of time. Corresponding method and computer program product are also disclosed.
