Measuring variables e.g. thermodynamic measuring variables, detecting device e.g. rain sensor, for motor vehicle i.e. car, has conversion units for converting area signals into measuring data signals and connected with optical conductors

摘要

The device (1) has a central evaluation device (4) staying in connection with optical sensor elements (3) and an electrical sensor element. The evaluation device has conversion units for converting measuring area signals produced in measuring areas into measuring data signals and a light transmitter formed with an LED. The measuring area signals are formed as optical signals that are transmitted from the optical sensor elements to the evaluation device by optical conductors (5, 6). The units stay in connection with the conductors. The optical sensor elements include polymer and/or glass fibers.
