## Overview

The Adafruit MPRLS Ported Pressure Sensor Breakout offers a highly accurate 0 to 25 PSI absolute pressure measurement with a durable stainless steel port for easy tubing attachment. Featuring a compact design (17.8x16.7x7.5mm) and a 24-bit ADC, it connects effortlessly via I2C to popular microcontrollers like Arduino and Raspberry Pi. Pre-calibrated and supported by example code, it’s ideal for DIY assistive tech, vacuum chambers, and precise environmental sensing.

## Description

We stock a few barometric pressure sensors, great for altitude and weather measurements. 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. The port is made of stainless steel and is 3.7mm long and 2.5mm diameter. It doesn't come with tubing so be sure to purchase some tubing to attach to the port. We've 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

Review: Easy to Integrate into RPi using Java - Successfully integrated into a Raspberry Pi used in pneumatic mast system. The outside diameter of the port is 0.1 inches. I installed the entire board into a section of PVC conduit and used an air tight connector to get the data out. Works well with Arduino and PI4J. All necessary information is on the Honeywell web site
Review: less than perfect - seems to work most of the time, sometimes it wanders off and has to be unplugged for a while. it's about the only pressure sensor I could find,

### ⭐⭐⭐⭐ less than perfect
*by L***L on February 25, 2021*

seems to work most of the time, sometimes it wanders off and has to be unplugged for a while. it's about the only pressure sensor I could find,

### ⭐⭐⭐⭐⭐ It is very accurate
*by R***O on February 25, 2022*

airport pressure = 29.8" Close as I need it to be, so the 0.007" is as close to zero as I can get, so I assume 0-25psi is a real range.
