3. 1
The Issue

4. Water Quality Degradation of surface water in Vietnam
Rapid insustrialization
Intensive agriculture and acquaculture
Substandard management of water sewage
Degradation and recession of groundwater
Drought
Salination
Water scarcity

5. Information Access National Water Quality Networks LED Notice Boards
Not very accessible
Not very easy to understand
LED Notice Boards
Limited quantity
No update about it
Low Public Awareness
Limited Crowd Participation！

6. 2
Our Ideas

7. Raise awareness on water quality Approach people to basic technology
Objectives
Raise awareness on water quality
Data can be record in a SIM card or sent by Bluetooth (compared with other products)
More vivid information such as photos and descriptions
Connect and share
By letting people participate in the monitoring process
Users can develop their own device and add other parameters
Approach people to basic technology

Real time water quality monitoring

10. Hardware Real time water quality monitoring adapted to children
Use basic parameters to introduce environementales sciences
Other sensors can be added easily
The information can be saved or shared
The price may be affordable for schools or groups to buy

11. Hardware pHmeter Turbidity sensor Color sensor ARDUINO board 1 2
Arduino is an open-source platform used for building electronics projects
- Changes may alter substances to a more toxic form
- Control is necessary to ensure satisfactory water clarification and disinfection 1 2
Electrical conductivity + temperature sensor 3 4
Turbidity sensor
Turbidity is a measure of the amount of suspended particles in the water
It can control salination (e.g. sea level raise) and thermal pollution
Color sensor 5
Many parameters can be determined by changes in color of paper strips

18. Objectives Again
Citizens gain more knowledge about water quality in terms of current situation，detecting and improving
Crowdsourcing facilitates information collecting and sharing
Data helps compare and choose from limited sources of drinking water
Public awareness prompts governmental actions resolving water pollution
