Abstract—Sensors and actuators are used, often networked in a distributed control system, in a number of applications ranging from industrial automation to environmental condition monitoring/control, to intelligent transport systems or to homeland defense. The paper reviews the implementation for embedded systems of a sensor network interface, based on the emerging IEEE 1451 family of standards, targeting smart transducers, i.e. sensors or actuators integrating on-chip also the mixed-signal processing chain and a digital communication host port. As application case example, a networked system of hydrogen sensors to monitor the gas leak in hydrogen-based vehicles is presented.
