Check your local water quality and become a custodian of our living environment. Shine a light on water using sensor fusion and sophisticated data visualization techniques. Our dream is to improve the quality of our living environment through a community-driven ecosystem focusing on surface water. We safeguard the use of our surface water as a natural resource for our drinking water and recreation. Our aim is to create a community of practical people that care about the general environment and are willing to contribute by safeguarding the well-being of the surface water. We call these people the custodians of our living environment. Custodians use a smartphone to capture a photo of their local water situation and upload it to our server. We can then collectively picture the issue. This can form the basis of future water quality monitoring. Above all, this can inspire local governments to make appropriate policies. Water policy faces challenges because numerous stakeholders have conflicting demands and opinions. It is essential for society's overall health that we rely on data-driven decision-making and policy creation grounded in a shared reality. Collectively we face a challenge in addressing the real issues based on relevant, accurate and current data. We combine several affordable sensors in devices measuring the quality of our living environment, such as floaters that measure surface water quality and pinners that measure soil moisture quality. We apply many of these devices in a sensor network and store the data in an immutable database through blockchain technology. Monitor our living environment, share data, and collect mining rewards. In addition to the data itself, the method by which it is presented is crucial. We help communities understand water quality data, existing and from our sensor network in real-time using sophisticated data visualization techniques. We need your help to collectively shine a light on water. aqa.earth
