Recommendation for windshield rain sensor
Recommendation for windshield rain sensor
(OP)
Hi All -
Can anyone recommend a source for a windshield rain sensor ? Preferably one that doesn't require a 10,000 unit purchase :)
I'll take pretty much any technology, resistance, refraction, whatever. I just want to retrofit an auto-trigger for the wipers on our cars ... Interfacing to a small microcontroller shouldn't be too much of a worry. One pin for the output relay, one for an enable switch and one or two for the sensor input.
Thanks -
Dean.

Most of the commercial ones on the market seem to use an IR LED and photo-transistor setup.

Starts at $129, for about $8 in parts and some code :)
