Adafruit MPRLS Ported Pressure Sensor Breakout - 0 to 25 PSI

This Barometric Pressure Sensor with Metal Port is an excellent solution for measuring altitude, weather, or air pressure in confined spaces. Its stainless steel port allows for easy attachment of tubing, making it ideal for applications like DIY Sip & Puff interfaces, vacuum chambers, or other pressurized containers.

Unlike most barometric sensors, this one uses I2C, making it simple to interface with microcontrollers such as Arduino and Raspberry Pi. It features a silicone-gel covered pressure sensing gauge with a pre-calibrated 24-bit ADC for high-precision readings. This sensor measures absolute pressure in the range of 0 to 25 PSI, which is well-suited for most atmospheric and pressurized environments.

Key Features:

• Stainless steel port (3.7mm long, 2.5mm diameter) for easy tube attachment (tubing not included)
• Uses I2C communication for easy integration with microcontrollers
• Measures absolute pressure from 0 to 25 PSI
• Pre-calibrated 24-bit ADC for accurate pressure sensing
• Includes 3.3V power regulation and level shifting for compatibility with a wide range of microcontrollers
• Great for projects like Sip & Puff interfaces, weather stations, and vacuum chambers

Technical Details:

• I2C Address: 0x18
• Pressure Measurement Range: 0 to 25 PSI (absolute)
• Product Dimensions: 17.8mm x 16.7mm x 7.5mm (0.7" x 0.7" x 0.3")
• Product Weight: 1.1g (0.0oz)
• Updated with Adafruit Pinguin silkscreen for better legibility (as of November 22, 2023)
• Includes application notes and datasheets for Honeywell MPR series micro pressure sensors

This sensor is mounted on a breakout board, making it easy to use with various microcontrollers and microcomputers. With available example code and libraries for Arduino and CircuitPython/Python, you'll be able to start your project with ease. Don't forget to purchase tubing for connecting to the stainless steel port.
