Rain sensors and weather
stations are the smart way to irrigate your landscape. Most rain sensors have
small leather patches, calibrated to accept natural rainfall in a slow, measured way. The sensor has the ability to be adjusted for the amount of rain to
cater for the local conditions. Once exposed to rain, these patches will swell and send a signal to the controller to shut down. Once the patches have dried out, they send another signal
to resume watering. Some more advanced
controllers will allow you to adjust the time before they resume. Weather stations incorporate
the functions of a rain sensor, as well as taking temperature readings, every eight to 10 seconds, allowing them to
communicate with the minimum and maximum temperatures
to the Smart Controller. Because the Smart Controller
knows and understands the type of sprinklers
and plants that you have, it will automatically
work out how many minutes it needs to run. Talk about smart. Irrigation weather stations
are far more affordable than scientific-grade weather stations and they need a lot less
maintenance and calibration. This gives water managers
the tools to make better, more educated decisions on real data, as opposed to guess work and estimation. A weather station can save
on average another 30% on top of the savings of
installing a basic rain sensor. And like many other Smart
products, they’re easy to install. This provides a great return on investment of a Smart Controller. Discover more about the
