A typical mechatronic system consists of a multitude of components, and the sensors belong to an important and cru-cial class of such components. Optimal matching of the system components is implicit in the current definition of a mechatronic system. The focus of the present paper is the optimal matching of sensors with other hardware in the system. Sensor matching may be based on several concepts such as the operating frequency range (operating band-width), speed of response (and the corresponding rate of data sampling in digital conversion), the device sensitivity (or gain or data amplification), and the effect of component accuracy on the overall accuracy of the system. The pre-sent paper explores all these concepts and presents suitable approaches for sensor matching through those criteria. The relevant procedures are illustrated using case studies.
