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 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. We have 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.

FAQs:
Q: What is the pressure range that the MPRLS sensor can measure?
A: The MPRLS sensor can measure absolute pressure from 0 to 25 PSI.
Q: What interface does the MPRLS sensor use for communication?
A: The MPRLS sensor communicates over I2C.
Q: What voltage does the MPRLS breakout board require?
A: The MPRLS breakout board requires a 3.3V power supply.
Q: Does the MPRLS sensor come with tubing for the port?
A: No, the MPRLS sensor does not come with tubing. It is recommended to use 3/32" ID tubing, or 1/4" ID tubing with 3/32" ID tubing inside for a better fit.
Q: What software libraries are available for using the MPRLS sensor?
A: Adafruit provides example code and libraries for both Arduino and CircuitPython/Python for easy integration with your projects.
