Abstract
A current source sensor delivers detection information in the form of an intermediate signal by selectively applying a low-level or high-level current to a communication bus depending on the passage of a mobile target, the sensor including a sensitive portion detecting the passage of a of the mobile target, an electronic module controlling and shape signals coming from the sensitive portion, an embedded intelligence module designed, inter alia, to receive information from another sensor through a first signal present on the communication bus, the first signal being the sum of the abovementioned intermediate signal generated by the sensor and of another intermediate signal generated by the other sensor, wherein the embedded intelligence module is adapted to modify a first low level and a first high level of the intermediate signal, respectively, into a second low level and into a second high level depending on a the first signal.
