Depending on the type of pressure, the capacitive transducer can be either an absolute, gauge, or differential pressure transducer. The device uses a thin diaphragm as one plate of a capacitor. The ...

[James Eckert] got his hands on a Freescale MPR121 capacitive touch sensor. The chip in question ... and making more complicated pressure-sensing keyboards, whenever you need something super ...

In module 1 you will learn how to specify and use various types of pressure sensors for an embedded circuit. First, you will learn about piezoresistive, capacitive, and vacuum sensors. This includes a ...
