A summer of tinkering has culminated with a conductivity and temperature sensor that texts its data from inside a Gatorade bottle.
The plan is to submerge several of these along a stretch of the Monongahela River as part of a sensor-journalism class at West Virginia University. It’s a work in progress, but you can [see how things are going]. My job was to build a working conductivity sensor that would report its findings live. Here are the components and how I made it go.
Update: We actually deployed some of these sensors in a river!
