A major issue with many (commercially) breath controllers is the cleaning of the device. As moisture from breath accumulates fast, I wanted a breath controller that can be cleaned and dried easily - even the pressure sensor itself. My design avoids tubing and by removing a slider, the inner parts of the pressure sensor is accessible for easy cleaning and drying. If you remove the top plate with the hall-sensor everything can be rinsed under water.
