Abstract
A temperature sensor module includes a first temperature sensor configured for sensing the temperature of the environment, and a second temperature sensor configured for sensing the temperature of an eardrum. The first temperature sensor is a thermal diode, and the second temperature sensor is a thermopile. Preferably, the second temperature sensor may be a CMOS-infrared temperature sensor. The first temperature sensor and the second temperature sensor are both made of the semiconductor material such that they have same physical characters and same raising/falling temperature speeds even if entering into the environment with the different temperatures. Therefore, they are proofread easily, have a low manufacturing cost and consume low power.
