Goal: Create a low-cost sensor station design that can enhance traditional water quality measurements
There is no substitute for analyzing water samples in the lab, but the proliferation of low-cost microprocessors and sensors can add valuable context to traditional water quality monitoring. I am developing and using low-cost stream gauges that utilize open-source hardware and software to take real-time measurements of coastal streams (temperature, dissolved oxygen, water level).
The current design that we are testing in coastal NC (Inspired by EnviroDIY) varies in price between $500 and $1200, which means that we have the ability to gauge many more streams than has been possible in the past while using the same amount of money. Take a look at my GitHub to see some of the hardware and software that I’ve designed for this project.
