We 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 in making DIY assistive tech "Sip & Puff" interfaces or measuring the pressure within a vacuum chamber or other pressurized container. Unlike most ported pressure sensors, this one uses I2C, it's really easy to use with any microcontroller. Inside is a silicone-gel-covered pressure sensing gauge with a pre-calibrated and compensated 24-bit ADC. You can measure absolute pressure 0 to 25 PSI, which is a great range since ambient pressure here on Earth is about 14.5 PSI. This nice sensor is on a breakout board with 3.3V power regulation and level shifting so you can use it with any kind of microcontroller or microcomputer, from an Arduino compatible to Raspberry Pi
