We carry a few air pressure sensors, ideal for altitude and weather measurements. This pressure sensor is special because it is equipped with a metal connector. Unlike other pressure sensors, you can simply attach a pipe to it to measure the air pressure within a tight space. Specifically, we think this would be a great sensor for use with making DIY assistive tech interfaces "Sip & Puff" interfaces or pressure in a vacuum chamber or other pressure vessel. Unlike most ported pressure sensors, this uses I2C, it is really easy to operate with any microcontroller. Inside there is a silicone gel coated pressure gauge with a pre-calibrated and compensated 24 bit ADC. We have sample codes and libraries for Arduino or CircuitPython/Python. You can measure the absolute pressure from 0 to 25 PSI, which is a large range as the ambient pressure here on earth is about 14.5 PSI. The connector is made of stainless steel and is 3.7mm long and 2.5mm diameter. It does not come with hose, so make sure you buy some hoses to attach it to the connector. We placed this beautiful sensor on a breakout board with 3.3V power regulation and level shift so you can use it with any type of microcontroller or microcomputer, from an Arduino compatible to Raspberry Pi.
