An infrared thermopile sensor includes a silicon cover having an infrared lens, an infrared sensing chip having duo-thermopile sensing elements, and a microcontroller chip calculating a temperature of an object. The components are in a stacked 3D package to decrease the size of the infrared thermopile sensor. The infrared sensing chip and the microcontroller chip have metal layers to shield the thermal radiation. The conversion from wrist temperature to body core temperature uses detected ambient temperature and fixed humidity or imported humidity level to calculate the body core temperature based on experimental data and curve fitting. The skin temperature compensation can be set differently for different sex gender, different standard deviation of wrist temperature and external relative humidity reading.

Aspects of the subject technology relate to electronic devices having sensors such as pressure sensors. A pressure sensor may be integrated into an audio component of an electronic device such that the pressure sensor is fluidly coupled to an environment external to a device housing via at least a portion of an internal cavity of the audio component housing. The audio component housing may include an opening. The pressure sensor may be mounted adjacent to or within the opening. The opening may be sealed to prevent passage of gas or liquid through the opening. The pressure sensor may be integrally formed with an inner wall of the audio component housing. The audio component may be a speaker or a microphone.
