Can Rain Sensors Help You Save Money?

You may have an in-ground sprinkler system in Fort Lauderdale, FL installed on your property, but this doesn’t automatically mean it’s connected to a rain sensor. A rain sensor is an automated device that’s designed to shut off your sprinklers when it starts to rain. The device itself is not at all expensive. In addition to its affordability, it can also help shave up to 45 percent off of your water bills, conserve water and protect the environment. Another great thing about a rain sensor is it can be mounted in one of many spots outdoors, as long as it’s nowhere near roof eaves or trees and can collect rain easily.

How they work

Rain sensors are available as wired or wireless devices, both of which attach to the lawn irrigation system. How do they work? Let’s take a look:

  • One way they work is by using a collection cup to collect and weigh rainwater. Once the cup becomes sufficiently weighed down, it breaks the electrical connection to the sprinkler valves or pump.
  • Another approach is similar to the first one, but instead of weighing the amount of rainwater in a collection cup, the water is measured by an electrode.
  • The final way requires an expansion disc made of cork. When enough water lands on the cork, it expands and triggers the rain sensor to break the connection from the electricity running into your sprinkler system.

The advantages of using a rain sensor

From saving money to conserving water, here are the top benefits of using a rain sensor with your sprinkler system in Fort Lauderdale, FL:

  • Saves water: Although modern irrigation systems are designed to save water, you can save even more by using a rain sensor. Every time it rains a lot, it automatically shuts off your sprinkler, preventing water from being wasted.
  • Saves your lawn fertilizer: Did you know that a rain sensor can help save the fertilizer you’ve added to your lawn and your plants from washing away? It prevents overwatering that can wash essential nutrients from the grass and soil down the drainage system. When this happens, you end up having to add fertilizer again, thus spending more money on fertilizer.
  • Prevents disease and nutrient loss: Overwatering keeps plant roots from reaching deep into the ground. Too much water also washes away important nutrients from the soil. These problems make your plants and grass weak, unhealthy and vulnerable to disease.
  • Avoid groundwater pollution: Rain sensors can minimize water runoff, and therefore prevent groundwater and waterway pollution. Harmful contaminants like fertilizer, pesticides, pet waste and motor oil are the main culprits. Additionally, it prevents garden pollutants such as fertilizers and herbicides from entering into your groundwater system.
  • Increase sprinkler system lifespan: Because a rain sensor minimizes the amount of time your sprinklers stay on, it can significantly decrease wear and tear on your system.
