Solar-powered irrigation system aiming to make a difference


Blue Marble is a smart irrigation system, which waters gardens for 48 hours using only solar power even at night.

As temperatures continue to rise, crucial arable land is being lost. Drought poses an increasing threat to agriculture and irrigation becomes a dangerous issue in more and more regions of the world. All this ultimately puts a huge pressure on world’s food resources, and consequently threatens the well-being of the increasing population.

The UN called for immediate action and for the past decade has been heavily funding research on food security and desertification. This call stimulated various groups and independent companies to develop projects, or invent high-tech gadgets, which lead to new type of agriculture, a smart one, which ensures production of food regardless of the weather.

Alongside initiatives such as CoolFarm – the indoor farming facility by Philips – and Toshiba’s pest-free lettuce growing facility, smaller ventures opted for technologies that can help individuals. They can stimulate them to save water in their own back yard – not only reducing personal bills, but contributing to the global cause too. Yes, there are things you can do without the gadgets, but smart devices are also around to help you optimize your gardening approach.

One such device, or more like a smart irrigation system, is Blue Marble. It comprises of a central control hub, a remote drip system, sprinkler valves, and soil sensors. The control hub is wirelessly connected to a smartphone app, and controls the whole system. It allows adjustments to the settings according to current weather information and the data from the garden sensors. The app also allows manual operation.

The sprinkler valves and the drip system, which should be installed around the garden, and are managed by the hub, deliver just enough water either according to what the soil sensor say, or according to a timer.
