Help Figuring Out an Air Pressure Sensor for a Musical Composition

Projects General Guidance

I'm a composer of electroacoustic music and have a piece I've been working on where some tubing is hooked up to a trombone and a melodica. Essentially, via the trombone's F trigger, it can send air to the melodica so it can be played instead of the natural trombone sound. It was a fun experiment, but it was highly limited.

Onto Arduino... If I were to send that tubing into an air pressure sensor instead of another instrument, I could send the information to a program I'm familiar with (Max7) and have infinitely more options than I would have with a single melodica.

Short version: I'm in search of an air pressure sensor to measure readout from a trombone and to send into other software for processing.

There are lots of air pressure sensors out there. Absolute pressure sensors, differential sensors, and sensors for all kinds of pressure ranges from a few mbar up to 30 bar or even more. They come in various sizes and qualities. Some are fully water proof, others must be kept dry.

Do a search for "pressure sensor" on Google, or even on Adafruit or Sparkfun, and you'll get lots of options.
