1000 Flowers for the Planet - # 156 Use a Rainwater Sensor

In a nutshell, a rainwater sensor is a device that is connected to an automatic irrigation system, which is activated by rainfall. Once rain is detected it will shut off the irrigation system, hence saving water. They can be used in a domestic situation as well as commercial. At home you can use one with your lawn and/or garden bed irrigation systems to conserve water every time it rains. It will prevent overwatering of plants and lawn, which can cause the soil to lose nutrients and force the use of fertilisers to compensate (although by now we know to use natural fertilisers, don’t we?).

I have seen public areas – lovely big expanses of grass – being watered by giant sprinklers while it is actually raining. Therefore, not only domestic locations can benefit from a sensor. Local government bodies, councils, farmers, commercial and industrial estates can all help the planet by installing rainwater sensors. These areas are often not closely monitored by people purposefully watching out for when it rains so they can rush out and turn off the sprinklers or irrigation systems. But they can solve the problem with a rainwater sensor.

Using a rainwater sensor saves water, which means we use less of our transported natural resource, thereby saving energy and money, and helping the planet.
