I have had the rain sensor guage for six months now and it works as advertised; if it's rains, it will delay watering for a few days. This is a must have to save you money on your water bill and ensure you achieve the desired amount of one inch of rain a week for your lawn without watering your lawn after a recent rainfall.

It just works.
This little guy is extremely easy to set up and wire. My only complaint would be that it only comes with a 25' wire (I believe) and the instructions say not to extend it beyond that distance from the control panel. This limited me on where I could put it to a side of the house, only about 4' away (when it is better to place along a roof gutter or some place where a wall won't ever get in the way of the rainfall. Once it is wired to the control panel and you have screwed the cap up and down to desired amount of rain to shutoff sprinklers (there is a set of numbers you turn the cap to to stop sprinklers at 1/4" and on up) ...it's all setup. There are nothing else you need to do.

Good Deal for the price
Works as advertised. Requires a little fussing with, eg: "1/4"rain setting&/or 1/2vent for evaporation, etc; but once you figure out what works for you, per directions, it works very well.

This sensor integrates easily with the Rain Bird controller that I bought on the same order, and it will keep me from wasting water if the sprinkler system is set to run an automatic cycle immediately after a rainstorm.

Can this sensor be connected to the basic mechanical timer?
A shopper on Apr 21, 2015
BEST ANSWER: I don't know why not. It wires into the power side and just allows power (dry) or denies it (wet). All it is is an on/off switch.
Anyone know where I can purchase the moisture sensing disks separately?
A shopper on Dec 17, 2012
BEST ANSWER: Try Sprinkler Warehouse online
I'm confused by this specification, "Electrical rating suitable for use with up to six 24VAC 7VA solenoids plus an additional master valve or pump start that does not exceed 53VA"

My controller has terminals for a rain sensor but I have an 11-zone system. Does this mean that this won't work for some reason?
Tom L on May 31, 2012

Sprinkler Warehouse asked if I could answer your question.

The electrical rating is confusing but you can ignore it for your purposes. The rating means the sensor could be used to control the six solenoid valves directly (without a controller). This would be done by wiring them in parallel and passing them all through the sensor. You have a controller so this is not what you want to do.

You would connect the sensor to the sensor terminals of the controller and the controller would handle the current for the sprinkler valves in all of your zones. You could have hundreds of zones. The only thing the sensor does is inform your controller whether it has rained.

I don't know what are the electrical specifications for your controller but I am fairly sure its sensor input is well within the voltage and current rating of the sensor.

I hope this helps.

Does this come with the mounting bracket?
A shopper on May 11, 2012
BEST ANSWER: Yes, it comes with an articulating mounting bracket approximatel 8 to 10" long. It does not come with a mounting stake or post. I used a four foot tall piece of aluminum angle bracket and then drilled a small hole in the top end to allow a screw, lock wsher & nut to mount the Sensor. It seems to work well.
Is it wireless ?
A shopper on Feb 4, 2013
BEST ANSWER: No, it is not wireless. It comes with 25' of cable (3 wires), to which Rain Bird recommends you don't add any extension cable if you were thinking you might do so. The user manual that explains how it is wired is available from Rainbird under controllers.
does it work ?
A shopper on Jun 13, 2011
BEST ANSWER: The RSD-BEX Rain Shut Off works as advertised and is very simple to install. We recommend installation on all irrigation systems in an effort to reduce utility costs and that embarrassment when the sprinklers are running during a thunderstorm. If installing near public access or children locate out of reach. Seems to stimulate curiosity.

The wireless unit also works well. The downside I have found with the wireless unit is that the receiver unit does not have a locking door and if installed in a lockable cabinet (commercial sites) the signal strength is reduced and therefore limits the distance between transmitter and receiver.
dose this sensor have a wire?
sprinklers on May 10, 2017
BEST ANSWER: Yes, it has a wire (usually it is about 25 feet long)
Are sensors manufacturer specific or can you use any two wire sensor with my Hardie Raindial controller?
ronc32 on Apr 25, 2015
BEST ANSWER: They pretty much work with any system. The sensor creates an open in the ground circuit, so the system stops working because even though the valve is getting power, with the ground open, the circuit is not complete. Since this is a basic circuit concept it would work in any system with low voltage electrically operated selinoids.
Is this sensor normally close or open? I want to use it with ESP-Me controler box however I am warned that it needs to be normally closed and I am noy having any luck finding a answer to this question. Thanks
Shawn on May 17, 2013
BEST ANSWER: Normally closed.

From the specifications document:
The rain sensor shall employ an electro-mechanical actuating device designed to cause a circuit interrupt that temporarily disables the irrigation controller during periods of significant
rainfall. The device shall automatically restore the controller to a normal operating condition after a period of time subsequent to the
The device shall be suitable to be wired – normally closed (N.C.) – in series with the valve common; and, shall include a short-lead to allow wiring normally open (N.O.) when necessary.
Will this work on a sst 12000s smart Controller and will it still be smart?
layy b
Larry B on Apr 25, 2014
BEST ANSWER: The RSD sensor is not smart, just an on/off switch controlled by rain fall amount. The SST controller determines whether to water or not based on zip code, time of year (spring, summer, fall, etc.), temperature and rain fall. It would likely work but not as well as the SST weather sensor sold with the SST controller. I would ask Rainbird to get a 100% correct answer.
Does this sensor work with the SST-400i Rain Bird controller?
Mark B on Apr 14, 2014
BEST ANSWER: Many modern controllers (such as those from Rain Bird)
include built-in terminals for rain sensor lead wires.
Dedicated rain sensor terminals are usually labeled “sensor”,
“SENS”, ”S” or “SN” on the controller’s terminal strip.
Use the procedure below if your controller does NOT have
dedicated rain sensor terminals.
1. Disconnect the wire from the common terminal (“C”
or “COM”) on the controller’s terminal strip. Then
connect this wire to the red Rain Sensor lead wire.
2. Connect the black Rain Sensor lead wire to the
common terminal (“C” or “COM”) on the controller’s
terminal strip.
I have a Rainbird SST 400i controller. Is this the right rain sensor? If not, what do you recommend?
Sig R on Mar 17, 2012
BEST ANSWER: This sensor works flawlessly. It's easy to install & is easily adjustable.
I've had mine for 7 years and experienced no problems. I purchased one for my neighbor in May of 2010. He's very happy with his also.
Hello, I have an Rain Bird ESP6-SI sprinkler system controller. Does this product work with it?
A shopper on Jul 4, 2011
BEST ANSWER: I dont believe that your controller is designed to accept any Rain Shut Off. The rain sensors are a normaly closed circut switch. If your handy with low voltage electrical, the Shut Off should be able to be wired inline with the 24v power leads. The only problem with this is that your programming may be lost whenever it rains enough to activete the sensor unless the battery sustains the programming.
Will this work with a rain bird TBOS-BT battery operated controller?
A shopper on Jul 4, 2019
BEST ANSWER: Yes - The spec sheet for the TBOS-BT controller series states that it is compatible with the Rain Bird RSD-BEX rain sensor.
will this connect to my existing rain bird transmitter ? I am replacing just the outside sensor portion
Philip S on Aug 28, 2018
This is a hard-wired sensor, so won't communicate with a wireless rain sensor receiver. This rain sensor is designed to be wired directly to the "sensor" terminals on your rainbird timer. I believe you would have to purchase a complete new wireless sensor kit (e.g. http://www.sprinklerwarehouse.com/Irritrol-Irrigation-Rain-Sensors-p/rs1000.htm) to replace your wireless sensor.
Hope this helps.
Which sensor works best with DIG EVO100 Solar Digital Hose End Timer with Rain Sensor Connection?
Victoria M on Mar 18, 2017
BEST ANSWER: Hi there are several basic differences with the connection of a Rain Sensor. Some are directly Hard-Wired to the Controller. Others these days send a Signal to their Base Unit (which is wired to the Controller)

In the older days the only problem was if the Controller had dedicated Rain Sensor Terminals, or not.

Another thing to pay attention to, is a Rain Sensor is "Normally Open" or "Normally Closed" the early ones were always "Normally Closed" so that the Installer could use them to interrupt the VALVES GROUND on any Controller. Adding a "
can i run two controllers (one 6 station & one 4 station) off one sensor?
Jim H on Jun 3, 2014
BEST ANSWER: In a word: No. If each controller has it's own power supply, you run the risk of back-feeding, or a short circuit. With some controls knowledge, you could run two controllers with an isolation relay & 1 sensor, but these sensors are so inexpensive you may as well just order two. :-)

I need a replacement for an AquaConserve RTS-2 Rain/Temperature sensor (they no longer make product). Is this Rain Bird compatible with the AquaConserver ET-6/9/14 controller ?
A shopper on Mar 9, 2014
BEST ANSWER: Hi. Just wanted to send you some pics from our trip so far. Laura has most if them on her camera. First one is a ruin near an old monestary and castle near ballenskellig while the larger castle is King Johns in Limerick. Have already been thru Kilkenny, Kilarney, Waterford, and Cork. In Limerick for the next two nights. Hope everything is well in nebraska.

I have a pro-c - is this all i need or do I need another part at the pro-c?
Colin R on Sep 22, 2011
BEST ANSWER: I've been using the RSD-BEX with Rainbird ESP Modular controllers, so I can't speak speacifically about the pro-c, but the RSD=BEX provides both NO and NC contacts so any controller that will accept that wiring arrangement should work fine with the Rainbird rain cutoff.....hope this helps.
