Part of the Analog Circuits and Signal Processing book series (ACSP)


In this chapter we give an introduction and classification on some examples of physical sensors (devices placed at the input of an instrumentation system that quantitatively measures a physical parameter, for example pressure, displacement or temperature) and chemical sensors (devices which are part of an instrumentation system that determines, typically, the concentration of a chemical substance, such as a toxic gas or oxygen), describing their working principles and main characteristic parameters.
