Opto-electronic rain sensor, for a motor vehicle windscreen, has a radial arm at the housing for a temperature sensor using the rain sensor power supply to measure the windscreen inner surface temperature

摘要

The opto-electronic rain sensor (10), for a motor vehicle windscreen, has a temperature sensor module (18), with a sensitive surface (20), bonded radially to the housing (14) powered from the sensor power supply. The sensor has an arm (16) with bending elasticity, with one end bonded to the housing and the free end towards the windscreen with a gap between them.
