Solution
In order to prevent the loss of trees in cities, a data-driven recommendation algorithm is being developed as part of a project by AGVOLUTION and the Chair of Machine Learning and Data Analytics at FAU Erlangen-Nuremberg with the city of Erlangen, which determines when which city tree needs to be watered. In this way, the more critical trees are supplied first. Trees with a larger water reservoir can be watered later.
The mioty® radio technology from Fraunhofer IIS is ideal for this task. It enables reliable and energy-efficient transmission of data over several kilometers and is independent of other mobile phone providers. The sensors require very little energy and can therefore be operated for several years on batteries alone. Alternatively, they can also supply measurement data completely autonomously by equipping them with a small solar cell. The city of Erlangen is equipped with a relatively dense mioty® network, which is used for data transmission. The data for this approach is collected via 80 hardware sensor units from the company AGVOLUTION, which are distributed throughout Erlangen. They measure soil moisture, temperature and precipitation at 16 sensor locations.
