{"title":"Adafruit MPRLS Ported Pressure Sensor Breakout - 0 to 25 PSI","handle":"adafruit-mprls-ported-pressure-sensor-breakout-0-to-25-psi","url":"/products/adafruit-mprls-ported-pressure-sensor-breakout-0-to-25-psi","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.\n\nThe 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.\n\nKey Features\n\n\n0–25 PSI Range – Absolute pressure measurement (ambient is ~14.5 PSI at sea level)\n\nStainless Steel Port – 3.7 mm long, 2.5 mm diameter for attaching tubing\n\n24-Bit ADC – Pre-calibrated and temperature-compensated for accurate readings\n\nI2C Interface – Simple digital communication with any microcontroller\n\n3.3 V and 5 V Compatible – On-board regulator and level shifting\n\nSilicone-Gel Protected – Gauge element protected from moisture and contaminants\n\n\nIdeal For\n\nDIY assistive technology \"sip and puff\" interfaces\nVacuum chamber and sealed container monitoring\nPneumatic system pressure measurement\nAir flow and pressure differential experiments\n\n\nPackage Contents\n\n1× Adafruit MPRLS Ported Pressure Sensor Breakout\n\n\n\nNote: Tubing is not included. Purchase tubing that fits the 2.5 mm diameter stainless steel port separately.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":6437,"title":"Default Title","sku":"AF-3965","price":38.84,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
