摘要

The opto-electronic rain sensor (10), for a motor vehicle windscreen (12), has a temperature and air humidity sensor module (16) bonded to the housing (14) and connected to the rain sensor power supply. The two sensors are contained partially within a shrouding (18), with an opening for the temperature sensor to be pressed against the windscreen.
