Blow your brains out and see the light come on. Measures from 15 to 115 kPa (150 to 1150 mBar).
See this videoclip
for a demo !
Application examples
- Attach an airbag to the end of the tube and create a "squeeze" controller or an alternative to the bagpipe wind controls. Add TouchMini or
TouchMiniOn sensors for buttons,
a Slide for octave control and
a GForce2D-2 to capture body movements.
- Attach the tube to a
pillow filled with air and make music while you sleep - better yet, create a playpen full of such pillows
and use the sensor signals for audiovisual effects.
- Combine the Air sensor with
Hot&Humid and
Light
to create a full-blown climate control system.
Add Switches to control water valves.
