Have you ever wondered how you can shut off your irrigation system without running home at the first sign of rain? Rain sensors can result in helping the controller make sure you are #irrigatingresponsibly. It also through not irrigating can lower the chance of overwatering your landscape. It can be a huge help in making sure you are not wasting money as well.

Using Smart Irrigation Technology, rain sensors (or a rain switch) can either be hardwired into your irrigation system or connected wirelessly, depending on your system. They read the amount of rainfall through small disks stacked inside the sensor. They decide whether it has been enough or if your sprinklers need to step in and water more. This is determined by the rate of drying that can be adjusted by controlling the ventilation reaching the stack of disks on the sensor.  Some like the Hunter™ Rain-Clik®, have a unique Quik® response feature; this can command a controller to shut off immediately- not just at a quarter or a half inch; but right when the rain starts . Other products like the Rain Bird RSD-BEX have, multiple rainfall settings from 1/8″ to 3/4″ are quick and easy with just twist of a dial. If the rain was enough, the rain sensor sends a signal to your irrigation controllers telling it not to run.

Along with saving water, rain sensors can save money. Let’s say your irrigation system is programmed to run Mondays, Wednesdays and Fridays and uses about $10 worth of water for each cycle (station). Your landscape will most likely get all the water it needs for that week. By using rain sensors, you just saved $60 with 6 stations (average home) for that one week you didn’t use your irrigation system! Let’s extend the scenario to say that there are fifteen occasions over the year that the rain sensors keep your irrigation system from running. You just saved $150! Much of your household’s water consumption goes directly to watering your landscape. Sprinklers automatically deactivated after a heavy rain fall are an easy way to save in your yard.

Most plants root systems cannot stand to be waterlogged. Unregulated sprinkler systems will continually water which will lead to root rot and disease. Which can be a costly item for you; both through the gallons wasted and the cost of the plant to replace.  Using rain sensors prevents plants from becoming waterlogged from being overwatered by your sprinkler system after rainfall. Once the sensor’s disks have dried, the sensor will activate the irrigation timer again for daily or weekly watering.

This small device could save you; especially when you are using metered (city) water hundreds of dollars and gallons of water over a years’ time. If you have a sensor and you don’t think it is working properly call today and we can help you in troubleshooting. If you don’t have one, then get one!
