Rain Bird CPRSDBEX Wired Rain Sensor with Mounting Bracket and Wire

Wish it would rain more so I could be sure it works... LOL!! It has rained a few times but it was downpours so I can't say the adjustment works but I am sure it is fine. Easy install and good quality. I like it.

Sorinklerpartswholesale as a partner of Amazon sold us the sensor. Very fast shipment, 2-days, packaged as new. Easy to install especially on an existing Rainbird controller. Great value for the cost. Works extremely well to prevent the irrigation system turning on during a rainstorm. Would highly recommend.

Replaced my old sensor with this new sensor and hooked it up to my Rachio Controller. Works perfect. The sensor is about 60 feet from the controller. I connected the new sensor wiring to the existing wiring with wire caps/tape. I did not even bother to cut the excess leftover wiring on the new sensor. Just covered it with plastic bag. (i kept the excess wiring because I may need to move it in the future and may need the extra length). To test the sensor with the Rachio controller, you just press the lever/button on the top side of the sensor, and then you will get a "sensor activated" message from the Rachio controller (you'll get a message on your cellphone Rachio app). When you release the button, you'll get a "sensor deactivated" message. Ran into one problem during a rainstorm. I kept getting continuous activated/deactivated messages every 30 seconds on my cellphone app (Rachio). After looking at this further, I never adjusted the "vent ring" or "rainfall" setting. The vent ring was wide open, and this caused water to drain quickly. So, during the rainstorm, water would fill the sensor, causing a "sensor activated" message from Rachio controller, then water would quickly drain out thru the open vent ring, and then the Rachio would send a "sensor deactivated". This cycle kept going on every 30 seconds. Just make sure you experiment/test the best setting for the vent ring and rainfall setting. I ended up blocking about 90% of the vent opening by rotating the ring. BTW: Check with your city/county water department for rebates. Our city gives 75% rebate when you purchase water conservation devices.

It's a very good replacement for an old, worn out sensor. Only gave it four stars as the items wiring has been cheapened by very skinny gauge conductors making it somewhat difficult to connect to the original source wiring.

I bought this for our remote beach house in the hopes that it would reduce summer water consumption on the underground sprinkler system (which was originally on a Rainbird sprinkler controller. Later on I replaced that controller with an OpenSprinkler system that allows me to remotely access the sprinklers. Unfortunately what I found from experience is that while this does indeed trip if it rains, it can take up to 6 hours after the rain has started before it will trip depending on how light it is raining. Then it can take 24 hours for it to dry out. We tend to get a lot of times in the summer that it will rain lightly for a few hours in the morning and then stop raining. This is enough water to keep an established lawn green but this sensor won't trip on that. During the winter when it rains more heavily the sensor will trip but I turn off the sprinkler anyway. Nowadays I use a combination of remote observation of the lawn through a camera that faces out the window and remote programming of the OpenSprinkler controller based on periodically checking of the lawn. The optimal time for watering a lawn is around 2-3am which gives the water enough time to be absorbed into the ground before the sun comes up and dries all your expensive water that hasn't soaked in yet, off the grass. My advice is to skip this simple sensor and buy a Rain Bird SMRT-Y Soil Moisture Sensor. It can substitute in place of the rain sensor if your sprinkler controller has a rain sensor controller and measuring soil moisture is a more accurate way of preventing overwatering.

It’s very easy to install. I don’t know how well it works. I just put it on because we’re always underwater restriction here and so I’m trying not to waste water.

The is a great addition to any irrigation system and will save water on the rainy days. It's easy to install and only two wires to connect in the control panel. I would suggest cleaning them yearly and protecting them during the winter.

Works great. Replaced an old Orbit, just to try something different and see if it lasts longer.

rain sensor arrived promptly and in excellent condition. Functionally it works as per the manual and gives a wide variety of setting options for optimising post rain delays to watering cycle. Very happy with it.
