Checking & Changing the Rain Bird Rain Sensor

About the Rain Sensor

The Rain Bird Rain Sensor is an important component of a sprinkler system. It’s designed to conserve water by shutting off your irrigation system for 48 hours (about 2 days) after rainy weather. Additionally, it is also helpful regarding freeze protection because it shuts off irrigation whenever the temperatures drop below freezing.

The Rain Sensor is powered by a 651009 – CR2032 lithium battery, you can find these batteries at your local stores like Walmart or Kroger.  

Checking the Battery

Checking the battery life of your rain sensor is easy. In the rain sensor dashboard on the top left, you’ll find an icon that looks like a battery. You guessed it, that shows you the expected battery life. Below we have provided a picture of where you can find the battery icon. 

How to Change the Battery Out
  • You will need a flat head screwdriver to switch the battery 
  1. Locate the Sensor:  The sensor, which detects upcoming rainfall, is typically mounted on a 4” by 4” post on the fence closest to the controller. Alternatively, it can also be placed in a gutter or on the soffit of the home. The most popular location for the sensor is on a fence post for easy maintenance.  
  2. Unlock: On the bottom side of the transmitter there will be almost a “lock”, you’ll twist the lock, and attached to it will be the battery. 
  3. Grab a Flat Head Screwdriver & Replace: The easiest way to remove the old battery is to use a flathead screwdriver to pry the battery out, after it’s out you can place the new battery in there and lock it.
