Our project is Mekong river water quality monitoring. We want to assemble a hardware equipment to test some parameters of water, like PH, conductivity and so on. And then the data can be transfered to a phone application. There are also many other functions in the application, such as showing the water quality in a map, asking questions, showing some tips about water, etc. the SDG that is most related to our project is goal 6: Clean Water and Sanitation. And our selling point is the cominatino of hardware and software. Then it is easier for people to know the water quality information.It can also arouse people’s attention to the problem of water pollution.
