The sensor/transmitter contains a number of small, water-absorbent rings (they look like thick washers) and are stacked vertically inside the cylinder that is at the top of the unit. As these rings get wet they expand and physically push against a switch; when they dry they retract. The rain setting (1/8", 1/4", 1/2", 3/4") works by simply adjusting how much room there is for them to expand before the switch gets activated. For example the 3/4" setting leaves a lot of space for expansion so that you need more rain (presumably 3/4") before the switch is activated. The switch position is transmitted to the receiver wirelessly periodically. The rings can be removed for cleaning, etc. in case dirt of bugs or whatever might clog it up.
There is also a twist ring that opens and closes a small hole leading to the disks; this is to control evaporation and the drying out of the rings. If it's completely closed the rings dry out more slowly keeping your sprinkler controller off longer. I imagine you fine tune this according to the type of soil you have. (Clay soil holds water longer, sandy soil shorter).Read more ›
I was even able to piggyback the 2 sensor wires to another Irritrol RD-1200 controller thus allowing me to use 1 sensor for 2 controllers.
1. The sensor has died it no longer send the "wet" water signal, it poured yesterday but no signal. It's dead. Poor quality!!
UPDATE: Exact one year later
I downgraded the rating from 5 to 2 stars for 2 reasons:
1. The battery died in the transmitter!! It's supposed to have a 5 year battery (coin 2032 x 2) but after one year it's dead. What a pain to climb to the roof to replace the battery. Lets see how this ones goes. BTW the battery has some grease on it which is normal to keep the water out from it.
2. When it rains, the "don't water" signal signal sent to my hunter watering system doesn't last very long. The receiver dries out pretty quickly within a day. So say it rained HEAVILY today buy tomorrow evening the don't water signal disappears and it sends a dry signal. The lawn shouldn't be watered for atleast a week due to the heavy rain! Now since it's sending a dry signal the irritation system waters the lawn on the next cycle a day or so later. It "wet" signal doesn't last long enough when it rains heavily. (I've rotated the sleeve on the receiver to cover the hole so it takes longer to dry, I've set the sensitivity to maximum YET it dries real quick for a heavy rain).
First up I found this on plummersstock for under 45 bucks.
Works great with Hunter Pro-C. Just turned off the power, connected the white and brown wires to the sensor terminals (make sure you remove the short plate on the sensor terminals before connecting the wires), then connected the red wires to the 24V AC terminals below the SEN terminals, turn on the power and your done. Took me five minutes.Read more ›

It works fine. Set it for the minimal rain detection to avoid the sprinkler coming on while it is raining. A little tricky connecting the wires. Read morePublished 14 months ago by Murray
