Pressure Sensor with MIDI Expression I/O

Post by stub »

I have a couple of these MPX2010 pressure sensors from a failed Breath Controller project.

I'd like to be able to use them with the MIDI Expression i/o.

1. Would this work?
2. How would I solder this to a TRS plug? Are any additional components (resistors, capacitors, etc.) needed?

That part is not a good match for MIDI EXPRESSION as it requires 10V. Sensors are cheap. Look for one that uses.a.3.3v supply. The MIDI EXPRESSION manual has wiring diagrams in the back. A pressure sensor would likely have the same connections as a Hall sensor.

I'm afraid I'm a little out of my depth here. Would anyone be willing to recommend a good breath pressure sensor (one with a good sensitivity range for breath control), that uses a 3.3V supply?

I'm not familiar with the pressure specs, range, units, values, etc.

Am I correct in assuming that because MIDI Expression is taking care of some of the range & slope calibration, that other components like resistors or pots aren't needed?

I can't recommend a sensor, but I can confirm that you indeed wouldn't need any resistors or pots.

Thanks, Rob.

I'll report back when I get around to selection and testing.
