Automatic sprinkler system controllers are scheduled to go in and out on any given day and at any given time. The driver did not know whether it is sunny and dry or raining outside. For this reason, every lawn sprinkler system must have a rain sensor.The rain sensor determines whether or not enough rain has occurred in order to skip a cycle of irrigation. There are three basic types of sensors rain. They all serve the same purpose: keep your system to avoid over-watering your lawn or garden. How? The electrical connection between the sensor and controller sprinkler system is interrupted when a certain amount of rain that activates the device. The sensor is broken electrical connection so that electricity can not flow any of the sprinkler valves or to begin a bomb (if your system is in a hole without a pressure tank). One type breaks the connection by the weight of water in a cup of rain collection. The problem is that such leaves, twigs, or the occasional lizard find their way into the collection cup and, therefore, turn off the system.The following type electrodes used to determine how much water is consumed in the collection cup. This kind of rain sensor device also has a problem with the system for collecting things other than rainfall in the collection cup.The most common type of rain sensor used by professionals is the expansion of disk drives. This type of sensor does not use a collection cup, but rains disks causes cork to expand. This device uses a pressure switch to break the electrical connection. These can be adjusted in increments of "the desired rain fall. This adjustment is typically set to turn off the sprinklers after "of rain has fallen.The most important aspect of installing a rain sensor is where to put it. Must be installed in an area that is free of trees, most of the ceiling hangs, or anything else that may block the rain to reach the sensor. If it is a sensor cable, placement is usually near the sprinkler controller. The cables should be connected within the controller valve wiring panel. This allows for easier settlement of electrical system problems as the sensor can be easily disconnected.In recent years, wireless FM rain sensors have become very popular. Although they are more expensive than wired devices, ease of installation and increased placement options offset the cost. Most units come with wireless bypass switches built into the device. Some drivers also offer digital by-pass options for both wired and wireless devices rain sensors.No issue the kind of rain sensor type you choose, all rain sensors offer many advantages over non-detector add this to your automatic system sprinkler. Some of the immediate and long-term benefits include:

? Save money. Whether you pay for drinking water or electricity to pass a pump running, money-saving time more than pay for the rain sensor.
? sprinkler system extends life. Irrigation systems are composed of moving parts. If the system parts are used less frequently (during the rainy season), which last longer.
? Protect Water Resources. By limiting the use of most of its sprinkler system, sensors reduce excess rain water runoff carrying fertilizers and chemicals to control pests in our water supply.
? Conserve water. Less water is wasted when it takes less additional water for their lawns and their garden.How much money can be saved with a rain sensor device? Vary depending on their source of water (city, back to claim, or so) and where you live (cost of water, electricity tariffs, climate). Here is an example that demonstrates the benefits mentioned above:

Seminole County, Florida.
System description:
? Designed to irrigate a quarter-acre of grass and scheduled for implementation "of water each time the system works.
? This timetable would be equal to 6788 gallons per irrigation cycle.
? This system (in the city of Water) pays $ 2.30 per thousand gallons.
? Whenever the rain sensor interrupts a cycle sprinkler, you save $ 15.61

According to a recent survey in Florida, using a rain sensor device average 45% savings in water for a single family residential usage.The water the next time you see a sprinkler system running in the rain, now we know they do not have to be that way. Sensors rain are affordable solutions to preserve our water, protecting our water resources, and saves money.Craig Borglum CIC / CID / CLI is a certificate and license Irrigation Specialist in Central Florida.
