Best Wireless Rain & Freeze Sensors for Sprinklers and Irrigation Systems

Wireless Rain Sensors

According to the EPA, as much as 50% of water used outdoors is lost due to a number of factors with irrigation being a key culprit. Water wastage from irrigation can happen for a number of reasons, such as faulty water fixtures and inefficient water usage.

If you live in an area that gets unpredictable weather then a wireless rain and freeze sensor is one of the most effective ways to help conserve outdoor water usage. You aren’t just doing the environment the favor, you are also doing yourself a favor by reducing unnecessary utility bill spending. Here are three wireless rain and freeze sensors we suggest to look at.

Best Wireless Rain and Freeze Sensors

The purpose of a wireless rain and freeze sensor is to automatically adjust your backyard’s irrigation or sprinkler level based on the upcoming weather schedule.

Rain Bird WR2 Wireless Sensor Kit

Rain Bird is a household name when it comes to irrigation automation. The WR2 is a great purchase for most if not all house owners. It is easy to install and also comes with great signal reliability, which is important for fast responsiveness against incoming rainfall.

One pain point that people may have when using a wireless rain and freeze sensor is the programming. Well, the Rain Bird will ease such concerns with its simplified programming. You can use the clear LCD screen on the controller device to easily configure settings such as rain and temperature set points, as well as monitor signal strength and battery life.

Orbit 57071 Rain and Freeze Sensor

The Orbit 57071 rain and freeze sensor is another easy-to-install device that will automatically stop your lawn sprinkler system as soon as rain is predicted to fall in your area. One aspect we like about this device is its signal strength.

For example, some homeowners mentioned the sensor synced really well with the controller despite a concrete well separating the two devices. The distance the wireless signal can reach up to is about 200 feet (this will be shorter if there are more obstacles between the controller and the sensor device).

Rachio 3 Smart Sprinkler Controller

If you are looking for a smart home device then look no further than the Rachio 3 Smart Sprinkler. This WiFi connected system will automatically adjust your yard’s irrigation system by taking into account a number of factors, such as rain, wind, freeze, and saturation levels.

It’s also different from the other two devices because it takes a proactive approach. It automates the irrigation schedule by taking into account weather prediction in the upcoming days and weeks. The other rain and freeze sensor devices are more reactive because they react as soon as rainfall or a drop in temperature is detected.

The Rachio 3 also comes with a smart assistant app where you can control the irrigation system manually, and the cooler part is that it will also help you manage the irrigation schedule by zones. This is extremely useful if you are growing a range of plants that have different watering needs. For example, you may want to set up a separate zone for the flower bed and vegetable garden.

Common Questions About Wireless Water & Freeze Sensors

What are some common questions that people have when it comes to using and purchasing a wireless water and freeze sensor? Read below to find out.

How Does a Wireless Rain Sensor Work?

A wireless rain sensor contains features that allows it to monitor the surrounding temperature and rainfall conditions. When any of the two conditions hit a certain limit, the sensor kicks in and sends a signal to the irrigation controller to stop the sprinkler system.

The wireless version of the rain and freeze sensor offer more flexibility in terms of location placement. These sensors are also less of an eye sore compared to their wired counterpart.

How Do You Install a Wireless Rain Sensor?

Before you install a wireless rain sensor, there are a couple of things you need to determine. First, you need to consider the best location to place the rain sensor. Typically, the best location would expose the sensor to the same rain and light conditions as the area that’s being irrigated. It should not be sheltered so don’t place it under trees or other overhead obstacles.

Do Wireless Rain Sensors Have Batteries?

Yes, wireless rain sensors typically come with long-life batteries that will last for many years. Some devices will allow the batteries to be replaceable, while others have the batteries sealed so you may need to purchase a new unit once the current one dies out.
