Thermometer/pressure sensor

[ghost]

I was wondering if it was possible to squeeze inside a tiny smd thermistor or even a pressure sensor. It would be a perfect match with digital compass.

The compass already contains a thermometer, though that one needs to be calibrated since it has some significant offset.

I don't think that an extra pressure sensor fits within the existing frame without dropping the compass/IR receiver. If you really want the pressure sensor, I'd recommend rolling your own PCB with the compass/IR receiver replaced by a pressure sensor. When modifying the PCB, make sure all components still fit within the mounting frame.
