The Coqui: a simple device to read a sensor via an audible tone. We're exploring using audio frequencies to convey sensor readings -- like a modem, but even simpler -- in order to make sensor readings more accessible for people (or to enable data transmission over ubiquitous audio jacks on PCs and smartphones)

For example, a Coqui can be built to measure:

 - [Conductivity](https://publiclab.org/notes/donblair/09-30-2014/coqui-bbv1-0-testing-conductivity-of-a-solution) (this capacity included in Coqui Classroom Kits)
 - [Temperature](https://publiclab.org/notes/donblair/09-30-2014/coqui-bbv1-0-using-a-thermistor-as-a-temperature-probe)
 - [Light](https://publiclab.org/notes/donblair/09-30-2014/coqui-bbv1-0-assessing-ambient-light-with-a-photoresistor)

## Get Help

Here is where we'd put our curated FAQ. Undecided whether this would look like a research note that we add to or a list of questions with a special tag that others are unlikely to use. I think if we use questions there needs to be a way to mark an "answer" even if it's a staff member compiling the best bits and pieces from the comments to make one cohesive answer"
