This paper presents a modeling of intelligent

sensors based on a representation of the sensor by services

it uses or it proposes, and by its User Operating Modes

(USOMs). This modeling is used for the definition of the

reactive layer of distributed agent based intelligent sensors.

Our area of interest is the agent-level layer in which the

concept of IIC (Intelligent Instrument Cluster) is defined.

An application that uses fuzzy-based intelligent sensors is

presented in order to illustrate the concepts.
