Taking water management to the next level, the proven Irritrol RainSensor Series makes watering in the rain a mistake of the past.

With its compact design and host of convenient features, the RainSensor Series is the perfect complement to any standard controller.

Works, but for how long?
The RS 1000 rain sensor works, and it's easy to install. So why three stars? This is my second sensor; the first one quit working after about 5 years. The problem seemed to be in the transmitter, but there's no way to replace only that piece. You have to buy the complete set.

Super Compatible
This device was easy to install and operate on both the Rain Bird ESP-TM2 and ESP-Me. Both controllers were purchased new in 2017. I am very happy with SprinklerWarehouse for the fast delivery and price.

Dead after 2 years
Purchased the RS1000 from Sprinkler Warehouse in July of 2019. At the start of this season (less than 2 years later), I started having issues with the connection between the base and sensor (the signal light is off/blinking). Thought it was the batteries on the sensor. They registered low - 3V batteries at 1.5V. Changed them, all was well for two days, then the signal dropped again. The sensor is not too far away - maybe 25 feet. Disappointed in the overall service life of the Irritrol wireless rain sensor.

Water saver!
Easy installation. I need to adjust the “dry out” rate as we got a 1.5” rainfull but sprinklers ran 2 days later. Only had it installed for 1 week but seems to work well.

Functions as desired
Running wires from my basement to some exterior spot would be problematic, so this wireless option came in handy. I was worried about signal getting through several walls and floors, but the low frequency used seems to handle that fine. Since I have 2 valve controllers, I purchased 2 of the units, then reprogrammed one of them to receive from the same sensor. That way I only had to mount one sensor, but could keep both valve controllers electrically separated.

The instructions have a minor confusing point regarding having to reset the receiver after a power failure. You actually don't have to, as the receiver is just assumes at power up that the transmitter/sensor has a dead battery until the first signal is received. I.e., it has no history of receiving any "I'm Alive" signals from the transmitter until the first one comes. So no need to worry about that.

Several options provided for attaching the transmitter to a gutter or whatnot.

The one irritating thing is that the transmitter is supposed to be disposable. The battery lasts 6 years, then you buy a new one, assuming the same product is still being made.

can I just buy the Irritrol RS 1000 outside rain sensor?
A shopper on Jun 17, 2015
BEST ANSWER: The outside sensor , which basically transmits the rainfall to your sprinkler control box, needs the other half of the sensor system to function. The rain sensor receiver connects to the sprinkler zone control box to interrupt your control box programming when it rains. The rain sensor system saves you money and doesn't give your neighbors the impression that you are made of money because you are watering your lawn when it is raining.
Is installation of irratrol
wireless rain sensor difficult?
A shopper on Aug 21, 2014
BEST ANSWER: Installation of the sensor is easy. I did that myself. But, to install the receiver, it has to be connected to the proper terminals in your irrigation.controller. If you don't feel comfortable with this simple electrical work or have the controller manual to guide you, I'd suggest to hire someone who can do it for you (it takes about 10 minutes for a pro to do). I hired that person, and the device works perfectly.
I have an RS 1000 Toro wireless rain sensor that activates just fine, but it quickly (less than 24 hrs.)dries out after it rains and thus sets the system back to normal. When it rains I want to skip a day or two before going back to regular watering. Is this due to the senor (6 yrs old). If so can I buy just the sensor part? Thanks.
Lloyd G on Jul 1, 2016
BEST ANSWER: I only recently got the sensor but from what I see it has no capability to help with a long delay in returning to "normal" condition. I think that for what you want you would need a soil moisture sensor in addition to or in place of the rain sensor. I do not know enough about soil sensors to advise more but no doubt Sprinkler Warehouse does. I would think that it would be possible to use both types in the same system. I am in LA so not much rain here anytime soon! Good luck.
can I purchase just the eave attach part for the rs1000?
Jim B on Apr 18, 2016
BEST ANSWER: The part that attaches to the eaves is the sensor plus transmitter, this unit senses if it wet [with rain] and transmits a signal back to the base receiver unit that stops and starts the irrigation programme.
I would guess that if you have a base receiver that accepts the transmitter pulses, then you should be OK.
However you need to check for component compatibility. Check with the manufacturer and read the instruction manual.
Can I purchase just fabric washers for the RS1000?
A shopper on May 5, 2017
BEST ANSWER: Hi, unfortunately, we do not carry the hygroscopic replacement discs. I apologize for the inconvenience. Thanks!
I have 5 Irritrol controllers. Do I need to buy a separate sensor for each controller? Or can serve at least 2 or more if wired accordingly?
Aaron D on May 9, 2013
BEST ANSWER: You only need one sensor for as many controllers as you may need. Just connect each controller with the sensor the way it is described in the manual and it will interrupt all of them simultaneously when it rains.
can it be use with a hunter clock?
A shopper on Mar 22, 2012
BEST ANSWER: It can be used with pretty much any clock that has electric valves.
It's basically like putting a switch (that turns off when it rains) in series with the common return (ground wire) for the sprinkler valves. When it rains, the return circuit is open, so even though the clock is still cycling through its normal program, the valves are disconnected.
A shopper on Aug 16, 2011
BEST ANSWER: I would say at least 3 years. Our works perfectly
Why does the red light stay on even though it is very dry?
A shopper on Jul 24, 2019
BEST ANSWER: Most of the time it is due to the humidity in the air. If it is very humid the leather discs in the sensor do not dry out, but either does your soil.
How to troubleshoot when signal light is off?
Joe L on May 4, 2019
BEST ANSWER: If the light is off the transmitter needs to pair with the receiver again. Unplug the controller and then plug it back in again. Then push the small antenna on top of the transmitter until the signal light is green and sensor status is red.
The company that installed our irrigation system also installed the Irritrol Rainsensor units, but the OUTSIDE unit has failed and I would like to buy a replacement OUTSIDE unit. Is that possible?

I need a replacement cork for a Irritrol RS1000 rain sensor how much is it and how do I order it?
A shopper on Jun 22, 2016
I have a irritrol RS1000 for my rain bird and the plastic ring around the transmitter has broken . I wonder if I can purchase just the shell for the transmitter because my electronics works fine?
