White paper: Barometric pressure sensors for consumer electronics
The last few years have seen a remarkable increase in the number of use cases involving barometric pressure sensors in consumer electronics devices such as smartphones, tablets, wearable devices, and various home appliances. Today’s barometric pressure sensors are so incredibly accurate that they can determine altitude to within just a few centimeters. This, coupled with low-cost manufacture, has made these sensors the mainstays for motion tracking, enabling what had previously been solely the realm of science fiction. In this white paper you will learn how the two primary types of technologies used for pressure sensors, capacitive and piezoresistive, and subsequently, focus on several applications and key requirements.
