  • As someone who has been doing a good bit of fermentation lately, I can tell you that those bubble airlocks create an audible, distinctive sound for each bubble. Furthermore, the airlock shakes (vibrates) noticeably as bubbles pass through. I think it might be interesting to compare the accuracy of using either a sound or vibration sensor. The setup would be very similar to what you already have.

No public wish lists :(
