There is a saying in electronics engineering world: "Every sensor is also a temperature sensor."
What this means is: almost every electronic sensor is affected by it's temperature- from expensive image sensors to cheap MEMS accelerometers and gyroscopes.
That is why many of digital sensors also report their temperature, although that is not their primary purpose- so that current temperature effects on the measured result can be calibrated out either in sensor's logic, or by host software.
- gnipgnip 10y agoErm, you can't calibrate out Boltzmann noise.
- planteen 10y agoI think OP meant calibrating out noise that leads to a bias (non-zero mean) that changes with temperature. Such things are common in many sensors.
- cperciva 10y agoYou can calibrate out the mean "light level" resulting from Boltzmann noise. You can't calibrate out the variance, but eliminating the mean noise is better than nothing.
