Unlike other pressure sensors, you can easily attach a tube to it, to measure air pressure inside a close space. 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. There is example code and libraries for Arduino or CircuitPython/Python. 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.

The port is made of stainless steel and is 3.7mm long and 2.5mm diameter. Adafruit have placed this nice sensor 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 TECHNICAL DETAILS Uses I2C address 0x18 0 to 25 absolute PSI measurement range App notes and datasheets for Honeywell MPR series micro pressure sensors Product Dimensions: 17.8mm x 16.7mm x 7.5mm / 0.7" x 0.7" x 0.3" Product Weight: 1.1g / 0.0oz
