- What's Included
The Orbit Wireless Rain/Freeze Sensor will add convenience, safety and water conservation to almost any automated sprinkler system. The sensor transmits a wireless signal up 200 feet away from the receiver which is connected to your sprinkler system timer. The communication is done via radio frequency (RF), which eliminates the need for a professional installation and unsightly wires. When a user specified amount of rain has fallen (from 1/8" to 1") or when temperatures drop below 37° F, the sensor will alert the sprinkler system timer to shut off. If rain is falling, stopping the use of your sprinklers will help to conserve water. If temperatures reach freezing, interrupting your sprinklers will reduce the hazards of standing water freezing on your driveway, sidewalks, and patios. The sensor has an easy one-step installation for either your rain gutter or any flat surface. The rain/freeze sensor is powered by 2 replaceable 3V lithium batteries (CR2032), included.
Important Note: This sensor is designed for 24 Volt Irrigation Timers only do not connect the receiver to 120/240 VAC.
Feature Control Switch and Manual Override Button
Located on the bottom of the transmitter, the three position feature control switch allows you to select Rain Sensor, Rain/Freeze Sensor and Sensor Off. On the receiver, the manual override button allows you to instantly stop the timer from watering or to allow watering when the rain/freeze sensor is active.
LED Panel Lights
Located on the receiver, the LED lights communicate the current status of the sensor.
The rain sensor can keep the irrigation system from starting or continuing after rainfall quantities of 1/8", 1/4", 1/2", 3/4", or 1"; the 1/2" setting is recommended. The time that it takes the rain sensor to reset for normal sprinkler operation after the rain has stopped is determined by weather conditions (wind, sunlight, humidity, etc.). These conditions will determine how fast the hygroscopic discs dry out, and since the landscape is also experiencing the same conditions, their respective drying rates will roughly parallel each other. There is an adjustment capability on the rain sensor that will slow down the rest rate.
The temperature at which the freeze sensor is activated is 37° F (+/- 2%deg) and is not adjustable. The freeze sensor feature can be bypassed by moving the switch (located on the bottom of the rain/freeze sensor) to the "Rain" position.

- worth the $$ Review by simon
worth the $$
had this for about 5 years now, overall very satisfied. orbit's customer service was good and they replaced the outside sensor since it was under warranty. wish the plastic outside sensor would be more durable. since it has been out in the sun for the past 5 years, the plastic became brittle and will break into pieces. hence making the expandable cork sensor useless.
I believe i only had to change the batteries once in the 5 years time, so that is reasonable.

Everything works as advertised. However, waiting one month for it to be delivered is a little excessive.

Wireless part works well. Still tuning for my area. The USA is divided into different plant based regions based upon weather patterns. It would be nice if settings were recommended based upon this. Anyways, happy with this product so far but it will take me a season to know how useful it really is.
