Measuring water cleanliness on an ongoing basis is expensive, time consuming, and inefficient. This struggle has given rise to many localized non-profit organizations that have taken up the challenge of water monitoring to preserve their way of life both now and for future generations. In most cases, this network of volunteers engages in manual water gathering and testing techniques that are (at best) slow, costly, and inefficient. One of these exemplary organizations is the Chattahoochee Riverkeeper, located in Atlanta, Georgia.
The Chattahoochee River Basin alone supports the drinking water and health of almost 5 million people, including metropolitan Atlanta. Now Ericsson and the Chattahoochee Riverkeeper want students to to join them to build a more sustainable environment for future generations.
Propose a creative idea using sensor technology to remotely measure water quality continuously in a specific location. Ericsson has the expertise to connect, secure, and transport data across a wireless network to the cloud. What they need are student ideas for devices that will cost no more than $200 to create that can gather and report relevant water quality data on a perpetual basis.
Please suggest a way to measure any combination of the following, as well as any other measures you deem important:
- pH level
- Dissolved oxygen
- Optical brighteners
The above seven measures are ranked from easiest to most difficult, and preference will be shown to students who successfully tackle difficult aspects of the challenge.
DEVICE CHARACTERISTICS: Your designed device must be waterproof, RoHS compliant, environmentally-safe, and low-power. Additionally, it should be easily deployable by a single person, anchorable in the river, and durable.
Please provide a diagram showing how to assemble your device. Additionally, describe your device and its intended usefulness.
