ABSTRACT:
An environmental sensing and ventilation control device is suggested, which is designed to control an electrically-driven system such as air intake flaps on an automotive vehicle. The sensor device includes a voltage divider with a sensor element. For the purpose of spatial separation of the means required for compensation of manufacturing deviations and the temperature sensitivity of the sensor element, as well as for provision of automatic compensation within the device, a microcomputer is connected on its input side to the divider point of the voltage divider via an analog/digital converter and on its output side with a number of switch elements. Each switch element co-operates with a different resistor so that at least one registor connects the sensor element resistance to ground.
