Abstract
A monolithic sensor arrangement includes a housing, a sensor integrated in the housing, and two or three connecting contacts deployed on the housing so as to provide a contact with the sensor. The housing also includes an integrated digital circuit includes a freely programmable digital processor, a program memory and a data memory, which are used to control and/or process the functionalities and/or the measured data of the sensor.
