Example: Open Hardware Water Sensors
Low-cost, open-design sensors for community water testing.
The story
Testing well and stream water is slow and costly, so many communities simply do not. The project designs sensors that anyone can build for the price of a few lunches.
All designs, parts lists and firmware are public, and workshops teach people to build their own.

About this project
A fictional open-hardware team designing inexpensive water-quality sensors that anyone can build and repair.
Impact / Why it matters
Cheap, open-design sensors let communities test their own water instead of waiting for someone else to.
Knowing whether water is safe usually requires lab tests that are expensive and slow. Communities that suspect a problem may wait months for an answer, or never get one.
Sensors with open designs can be built, repaired and improved locally for a fraction of the cost of commercial devices. Anyone can read the plans, check the method and share data.
More measurements from more places make it easier to spot pollution early, and they give residents evidence they can bring to local officials.
