What kind of signal would be most likely delivered by a digital sensor?

A digital sensor is specifically designed to output information in discrete values, typically represented as binary data—0s and 1s. This type of signal provides clear and precise data regarding the detection of an event or condition, such as the presence or absence of an object, a distance measurement, or a limit switch being activated. Digital signals are less prone to noise and can be processed easily by digital systems, making them ideal for applications that require high reliability and accuracy.

In contrast, the other types of signals mentioned are not characteristic of what a digital sensor delivers. An analog signal varies continuously and can represent a wide range of values, while a mechanical signal involves physical movement or force. A thermal signal refers to changes in temperature and does not fit the nature of a digital output. Therefore, the characteristic of a digital sensor is effectively captured by its output of a digital signal.
