Hi, A friend wants to put together a device combining an Android OS and a CO2 (and possibly others) sensor. He knows a bit about mechanical design, I know abit about Android (been playing with Linux for years). we lack electrical engineering skills (may need to find a friend to help). He found a relatively cheap CO2 sensor device ($100) that may potentially be wired to get the reading into an Android phone. I own a MyTouch that we can use for the prototype. The goal is to get a reading and send it using cell or data signal to another computer. Here are the docs on the CO2 sensor. https://docs.google.com/gview?a=v&pid=gmail&attid=0.1&thid=123abb92b11f7ce2&mt=application/pdf https://docs.google.com/gview?a=v&pid=gmail&attid=0.2&thid=123abb92b11f7ce2&mt=application/pdf Any tips on how to go about this project are very welcome!
