Author Topic: New house - Rain Sensor  (Read 989 times)

I was going to put this in the Elmer section but decided it would be better here.

My folks just bought a new house and the sprinkler system uses some type of sensor that is mounted on a facia board overlooking the backyard.  Apparently it detects rain and tells the main controller not to automatically turn the sprinklers on when there are days when it's been raining.

Here's my question;  How do I find out what frequency this thing is operating on?  I looked over the instruction manual and of course it says nothing about the operating frequency.  I refuse to waste time talking to the guys that installed the thing because I don't know how to say frequency in Spanish.

Any suggestions?

I'd first climb up there and find out what brand and model it is.  

How is it powered?  If off of AC, it might not be RF in the air, but uses Carrier Current over the power lines. 

Might not have to climb, if they've been given documentation...

I have a Rainbird WR2-RS Wireless Sensor and the "specs" are below -

UL, cUL, CE, C-Tick, and WEEE certifications
FCC approved spread spectrum 2 way radio transceivers with FCC Class B approvals

FWIW, I haven't noticed any type of interference associated with the sensor. I have no idea what frequency range the device operates in, but based on the physical size, I would assume it to be in the several GHz range.

Thanks for the information all of you.  The sensor didn't appear to have any wires running to it.  Next week I'll be able to spend more time with the manual and read it in-depth.  I never considered the possibility that it could be running on carrier current.  If I can remember I'll respond back with what I found just for your FYI.

Could you just imagine all the members of R.E.M. playing a concert wearing those big ol' sombreros.

If it is legal, it should have its FCC ID number on it.  That number can be used to look it up.
