Within the full paper, we will learn how a more detailed technology-driven assessment of distributed (and up to now) not assessable data ensures a profound way of understanding complex water ecology. Discharging of water pollutants as well as slight effects of continuous fertilizer input, e.g. induced by farming activities, may be monitored more quick and accurate and be traced back to the discharger.
Focal point is the description of the deployment of the Smart Data Hub (SDH), developed by the Innovator_Institute. This industry integration devices serves as easy to use enabler for smart production, in terms of a retrofit solution. Furthermore, it is quite handy and able to communicate with almost every existing sensor through a unique addressing option.
Beside this industrial application it is able to operate in the inner part of water buoys. So, traditional buoys (surface markers or moored buoys), can be equipped with the SDH-device to perform smart monitoring actions. The buoys are energized by a rechargeable battery and transmit the sensor signals efficiently among each other (slave-slave). So, there is no need for wiring, as just a few buoys directly communicate with the internet-capable master-buoy. Even in terms of signal losses all data are stored locally within the sensor grid and delivered to the master-buoy at a later stage, using an unique identification and time code.
As the SDH acts as a flexible sensor-hub, a wide number of common sensors may be attached to the buoy. This ensure a quite cost-efficient way for continuous water monitoring, without requiring extensive sample taking and delayed evaluation in a lab. As the SDH also acts as an auto-negotiating integrated amplifier: just the sensors have to be obtained, without any costly hard- or software.
