## Description

The Adafruit MPRLS Ported Pressure Sensor Breakout measures absolute air pressure from 0 to 25 PSI (0–172 kPa) via a stainless steel port. Unlike typical barometric sensors, the metal port lets you attach tubing to measure pressure inside sealed spaces — ideal for DIY assistive technology, vacuum monitoring, or pneumatic projects. The sensor communicates over I2C and features a silicone-gel protected gauge with a pre-calibrated, compensated 24-bit ADC for accurate readings. The breakout includes a 3.3 V regulator and level shifting for compatibility with both 3.3 V and 5 V microcontrollers. Key Features 0–25 PSI Range – Absolute pressure measurement (ambient is ~14.5 PSI at sea level) Stainless Steel Port – 3.7 mm long, 2.5 mm diameter for attaching tubing 24-Bit ADC – Pre-calibrated and temperature-compensated for accurate readings I2C Interface – Simple digital communication with any microcontroller 3.3 V and 5 V Compatible – On-board regulator and level shifting Silicone-Gel Protected – Gauge element protected from moisture and contaminants Ideal For DIY assistive technology "sip and puff" interfaces Vacuum chamber and sealed container monitoring Pneumatic system pressure measurement Air flow and pressure differential experiments Package Contents 1× Adafruit MPRLS Ported Pressure Sensor Breakout Note: Tubing is not included. Purchase tubing that fits the 2.5 mm diameter stainless steel port separately.
