About this item

The Adafruit MPRLS Ported Pressure Sensor Breakout (product ID: 3965) is a compact and precise sensor designed for measuring absolute air pressure in confined spaces. It offers a pressure range of 0 to 25 PSI, making it ideal for applications such as "Sip & Puff" interfaces and monitoring pressure within vacuum chambers. Unlike many ported sensors, it features a metal port (3.7mm length, 2.5mm diameter) for easy tubing attachment. The sensor communicates via I²C (address 0x18) and operates on a 3.3V power supply. It integrates a pre-calibrated, compensated 24-bit ADC and includes libraries for Arduino and CircuitPython/Python. The breakout board is equipped with 3.3V power regulation and level shifting, ensuring compatibility with various microcontrollers and microcomputers.
