Adafruit MPRLS Ported Pressure Sensor Breakout - 0 to 25 PSI POL_3pi Robots and Accessories Combinations of the four LEDsWe stock a few barometric pressure sensors, great for altitude and weather measurements. This pressure sensor is special because it comes with a metal port! Unlike other pressure sensors, you can easily attach a tube to it, to measure air pressure inside a close space. In particular we think this would be a great sensor for use with making DIY assistive tech "Sip & Puff" interfaces, or measuring the pressure within a vacuum chamber or other
