If you love gardening there is good news in store for you. Wilted plants thirsty for water could soon become a thing of the past, thanks to a new app that tells users if it is time for watering the plants.

The Koubachi Wifi Plant Sensor, which is placed in the soil of the potted plant, is connected with a smartphone app that alerts people if plants need watering, fertilisers or sunshine.

“There’s very little information when you buy a plant. Most of the time there’s a little sticker that will say it needs a medium amount of light and water every few days. But that’s very rough and doesn’t apply for most plants,” said Phillipp Bolliger, the inventor of the system and CEO of Koubachi AG, which is based out of Zurich, Switzerland.

The sensor collects data on the soil topography (eg moisture, light intensity and ambient temperature) and these information is then sent to the app. This app is currently available for iOS devices.


Bolliger said water monitoring is particularly important. “The problem people run into most often is that they give too much water — that’s the main cause of killing plants,” he explained in an interview.

“We run different experiments with a lot of different plant types in the greenhouse,” said Bolliger. “We have our experts assess the vitality of the plant. Then we verify our models given the actual expert analysis of the plant’s vitality.”

Each sensor costs around 100 euros. But it is not necessary to buy a different censor for each plant. They come with multi plant features. The sensor can run for more than a year on a single set of batteries.
The app, which is free, is available worldwide from the App Store. The sensor can be bought online at
