Anshare is a connected buoy which test water quality.

The outcomes can be shared via an app.

The buoy can indicate the quality of the nearest water spot.

Our aquatic environments are increasingly polluted. The reason for this is global warming and chemical spills. The risk? The proliferation of cyanobacteria which can be dangerous for animals and human beings. Anshare is a connected object which quickly analyzes water quality. If the user immerses the buoy, it analyzes various parameters, the results of which are transmitted to the competent scientific bodies via the mobile application. On land however, its color indicates the quality of the nearest water source. Anshare is designed to create a community based on this major issue and raise public awareness.

Anshare is a connected buoy that enables anyone to analyze the water quality of a river. Fishermen, boaters and even residents can take readings quickly and easily and send them to a community platform. The study site chosen for Anshare is the river Erdre, a body of water which is subject to pollution from pesticides and cyanobacteria (blue algae) and an important zone for water-based activities (leisure activities, watersports, fishing, boat travel, etc). The project put forward by Raphaël promotes an effort to raise awareness and involve citizens through data collection intended to protect the environment. It was in 1900 that Frank Chapman, a naturalist and ornithologist, inaugurated the first “participative science” initiative involving a survey of bird species. In 2009, there are over 350 academic articles based on this Christmas Bird Count. Even more important than the buoy itself, which is manufactured according to the principles of sustainable development, is the whole system of participation, involvement and empowerment which Raphaël handles masterfully.
