What is this ? Rain Sensor ?
 

I was clearing some leaves and found this. We recently moved into the house and have an irrigation system. What ever this is it is beeping about every 30 seconds. I am guessing it might be a rain sensor for the irrigation system. Not sure if the beeping sound is normal or if it is a rain sensor ??

That does not look like any rain sensor I have ever seen.

Mine looks like this and is mounted on a fence well above the ground.

Could be one of those beeping rods in the ground to deter gophers.

Looks like an ultrasonic solar powered Mole deterrent.

You must live near Echo Base.

Step on it and see what happens or just whack it with a shovel.











I agree with the gopher deterrent.

Might be a good time to contact the previous owner "off-record".

Thank them for the nice house but what other quirks might I be aware of and need to fix...

Looks like there is a brand name under the cover, I can't make it out. Maybe google it and see?
