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) [![IMG_20190123_111639_270.jpg](/i/28988?size=medium)](/i/28988?size=original) [![IMG_20190118_205609_421.jpg](/i/32338?s=m)](/i/32338?s=o) 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 ****
**** ## Education & Public Lab: Get Involved!

[You can learn more about this here.](publiclab.org/wiki/education) ## Getting Classroom Kits For Your School We offer a variety of tools and kits that can be used in educational settings. ****We offer a 10% discount on bulk educational purchases, and we are always happy to work with educators to make suggestions and prepare custom orders to meet your needs.**** (Embed links to buy Classroom Kits Here) ****This may change as we update store listings ## Assembling Your Coqui (embed Make video) For step-by-step assembly instructions,[ click here.](https://publiclab.org/notes/warren/03-01-2019/build-a-sound-generating-coqui-conductivity-sensor) ## Using the Coqui Here are some lessons, materials, and workshops shared by Public Lab contributors. Try them out or design and share your own. [activities:edu-coqui] ## 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"
