The F8652E digital output is available in a variety of formats. Unlike analogue sensors, where the output value is a value that varies continuously over the entire output range, digital sensors have only two output values, either “0” or “1”. A flick switch (touch switch) is one of the simplest examples of a digital sensor. When not pressed, a flick switch is usually an open circuit with infinite impedance, and when pressed, it becomes a short circuit with zero impedance.

F8652E When interfacing a digital sensor to a data capture device, a number of key factors must be considered that may affect the performance of the interface. As a result of technological advances, a wide variety of sophisticated digital sensors are available on the market, and today’s sensors are capable of generating a long series of switching state transitions. When using these sensors, the frequency characteristics of the output pulse train, and even the shape of the pulses, characterise the sensor’s measurements, thus making continuous measurements possible.
