Digital freeze sensor prevents watering in freezing conditions. Reduces hazards and damage from freezing water. It is universal and will work with new and existing sprinkler systems. Adjustable rain sensitivity with 5 settings from 1/8'' to 1''. Automatic rain delay with adjustable duration. 3 mounting options threaded, slip, and rain gutter.
With so many on offer these days, it is great to have a name you can trust. This item is certainly that and will be a perfect buy. The distributor have added some great touches and this equals great value.
You can trust this review, i hope you can try to buy this product and then you know this product good or no. Next time you can make a review for another people.
The sensor would stay triggered no more than 10 hours.
I bought this sensor and tried it several times under spring rain. The sensor will be triggered by the rain, but it took a while (about a half hour heavy rain) to start. That causes a lot of waste of water if your system happened to start during this time. I guess this is the shortcoming of this type (disc expansion) of rain sensor. In addition, the sensor supposedly can stay on for a period of 1 or 2 days depends on the evaporation setting on the sensor. I set the evaporation window to fully closed in order to test the longest delay time. After several heavy rains, the sensor can only stay on for no more than 10 hours. That means 10 hours later after a heavy rain, the system can still start to water your lawn. I am disappointed about this sensor. Nevertheless, the sensor looks pretty solid, and sleek.

Rain sensor
The rain sensor is hard-wired. There is also a model which is wireless. The hard-wired unit is wired to interrupt the electrical current going to the irrigation zone solenoids. There is no way to override it, so if it rains enough to trip the switch you have to either go up and re-adjust it, or just do without watering until it dries out. This can be bypassed by the user just installing a simple switch between the wires that go to the rain sensor, essentially bypassing the switch.
The switch does not contain a float mechanism. It works by rain causing expansion of some fibrous washers which in turn presses a micro-switch to interrupt the electrical current to the irrigation valves solenoids.
There are two adjustments on the switch- one for how much rain it takes to trip it and the other for how quickly it will be allowed to dry after it gets wet. There is a calibration on the side for how much rain is needed to trip it.
Overall the switch has...
Orbit rain sensor
I recently purchased [4] rain sensors and installed them on my drip-system controllers at my ranch.Amazon has the lowest cost/no shipping $/and fast delivery! The [2] sensors that i installed on 'old' orbit controllers[wired in series with the valves 'common'wires tested fine. however the [2] sensors that i installed on 'new' orbit controllers [which contained sensor switches and connection lugs] would not work until i added a jumper-wire from the valve 'common' lug to the 'right-sensor-lug.then these [2] sensors also tested fine.[i sent an e-mail to orbit related to this problem but never heard back from them].we will have to wait for the Az summer monsoons to arrive[jly-aug-sept] to actually determine that the sensors shut down the drip-systems during rain storms.if the sensors work as stated they will be a major improvement in our drip systems and a large water cost saving also!!
