Arduino MQ-3B Ethanol Sensor: Behavioral Neuroscience Research
Introduction Recently, I had the opportunity to collaborate with a university research lab to build some vapor sensors to roughly measure ethanol (EtOH) vapor within an operant chamber. This project was a lot of fun. With extremely limited circuit documentation on the web and never having personally used Arduino before, there were a lot of interesting hiccups I ran into. Overall, this project was a bit out of my wheelhouse, but with much determination, the finished product turned out rather nicely....
