I saw this on a house.....
This house has an underground water sprinkler so I was wondering if
this is some sort of rain gage but that's strictly a guess on my part.
And even if I'm right, I have no clue how it collects rain water.
Hey, I can be wrong, too. It's a hand washing detector. If you leave the
house without washing your hands, it sends a text message to the Department
of Silly Walks. The inspector will be by, shortly.

Well, all the correct answers have been taken so:
A target device for a UFO invasion?
Its a rain sensor. Inside are probably a stack of fiber washers around
a plunger. When the washers are wet, they expand, pushing the plunger
up and breaking an electrical contact, which in turn prevents your
controller from irrigating. When the washers dry out, contact is
restored and the controller will irrigate.
Its a handy device, since many irrigation systems are set to go on early
in the morning, when everyone is in bed and the water pressure is
highest. The water sinks into the soil, rather than evaporating in the
sun, so you need less water. Naturally, you aren't up at that time to
turn the controller off if it is raining.
