The readings taken by the pulse width modulated accelerometer at a fixed rate, generally at 1000 Hz (but this can be configured by a user based on the IC used).

In the figure below you can see the most common ones used with the Arduino. A pressure sensor usually acts as a transducer; it generates a signal as a function of the pressure imposed. I had already mentioned the common platforms for hardware to connect. Analogue, of course, has virtually zero latency, while the amount of latency in a digital system can vary depending on the processing qualities of a particular digital system.Small amounts of latency, however, are tolerable depending on the application.
