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 (this capacity included in Coqui Classroom Kits)
• Temperature
• Light

On this page, you can:

• Learn more about the educator community at Public Lab
• Purchase Coqui Sensor Kits for your classroom
• Get instructions for assembling your Coqui Water Conductivity Sensor
• Find lessons designed around the Coqui
• Get help from the FAQ, or ask your own question

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"
