Real-time water quality monitoring is usually a demanding and costly affair. Advanced sensors for phytoplankton and turbidity, for example, are expensive and often require regular maintenance. To enable a much more widespread use of real-time water quality sensing, WaterITech and WaterWebTools have joined forces to build a low cost and low maintenance monitoring system, which combines some of the most durable water quality sensors with advanced AI-based data processing. The solution is a seamless integration of our customizable data buoy and the online ASAP Metabolism tool, and provides a range of water quality indicators, which are relevant for understanding both real-time and long-term trajectories of the ecosystem state. We provide a complete, integrated sensor, data communication and software system - getting starting with real-time monitoring has now become a lot easier.
