Water quality

We’ve put together some affordable sensors and a small computer to measure and upload data about water temperature, acidity, and dissolved oxygen.

==Intro==

For monitoring ocean water, we’re using sensors from Atlas Scientific, connected to an Arduino programmed ESP32 controller board.
