com) has developed what they say is the world's first surface-mount technology (SMT) package for photodiode chips which not only allow the SFH 2200 A01 and the SFH FAA01 (this latter one has a daylight filter) to be mounted behind the windshield glass to perform as rain sensors (when a raindrop hits the windshield, the diodes detect a change in the incidence of light, and the number of drops affects the overall amount of light detected, thereby causing the wipers to work at varying speeds), but which facilitate manufacturing, as they've improved the moisture sensitivity level in the chips-which has nothing to do with rain, but with soldering.
