Sprinkler Rain Sensor

If you have a big garden or lawn, you have probably installed some automatic sprinklers to keep the greens nice and lively. While sprinklers can be very effective in keeping your lawn or garden water from getting dry, you still have to consider the opposite scenario: what about the rain seasons? In such occasions, sprinklers may end up over-watering your plants – which besides amounting to a waste of water, isn’t really good for the plants either.

Fortunately, there are now sprinkler rain sensors available on the market which can be used to suspend the operation of your sprinklers when it’s not required. Using these small devices, you can make sure your sprinkler does not excessively water your garden, while keeping everything automatized. Sprinkler rain sensors are very easy to install, and if properly adjusted they will simultaneously keep your lawn properly watered while helping reduce your water consumption. Even though choosing a sprinkler rain sensor is not complicated, it’s always a good idea making an informed decision, in order to make sure you are fully satisfied with your sensor.

Choosing the right sprinkler rain sensor for you

The first consideration when looking for a sprinkler rain sensor is whether to choose the wired or wireless variants. Wireless rain sensors are relatively new, but they are just as effective as the wired versions. They are easier to install, they have long lasting batteries, and they will certainly get the job done (unless you install them out of range from the sensor, of course); also, wireless sprinkler rain sensors are not necessarily too expensive, compared to standard rain sensors.

Regardless of whether you choose the wireless or wired variants, the installation process is generally similar. You will get a rain sensor and a receiver, which should be placed accordingly to their functions; the sensor should be in a strategic location in your lawn where it will be able to detect the presence and intensity of rain (so you need to make sure it’s not blocked by trees or roof lines). The receiver picks up signals from the sensor, and connects to your irrigation control box to make the necessary chances according to the detected amount of rain. Working together, these little gadgets can be very effective in diminishing the waste of water in your garden during the rain seasons.

When looking for the right sprinkler rain sensor, you should make sure it allows adjusting its sensitivity to rain. There are extremely cheap sensors available which lack this kind of function, but they’re not too useful… after  all you want to adjust your watering in proportion to the amount of rain, rather than shutting if off entirely just because a passing cloud happened to drip a little bit over your lawn. Ideally, you should also adjust your rain sensor according to other specifications, such as the type of soil and the weather humidity in the place where you live.

The benefits of using a good sprinkler rain sensor

A good sprinkler rain sensor will usually feature a wide range of settings, which you can adjust to suit the requirements of your lawn as well as the specifications of local climate and soil. For example, if your garden is on a clay-type soil, this kind of soil will not absorb as much water as a sandy soil would… and as such you will have to set the sensor to a higher threshold, so it doesn’t cut off the sprinklers after detecting just a little bit of rain. Conversely, if the soil in your garden is quite porous, you should configure the sensor to a lower sensitivity setting, so it won’t cut off the irrigation after detecting just a small amount of rain.

Most of the modern sprinkler rain sensors now available on the market also include a vent ring, which you can adjust to determine how long the unit will take to dry out and resent. This kind of feature can be used to great effect in order to match the climate and humidity in your area of residence; by doing so, you’ll make sure your sensor is properly configured and it will likely perform efficiently in all types of weather.

Remember, one of the most important things you need to do to make sure your sprinkler rain sensor is efficient is installing the sensor in a good location, where it will be able to pick up direct rain and send the signal to the receiver without interferences. But asides from installing the rain sensor appropriately, you should also make sure you test it and configure its sensitivity settings to match the weather and soil in your area of residence. Only by doing so will you make sure you save the most water, while keeping your lawn in the best possible condition.
