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 \u0026amp; Puff\" interfaces, or measuring the pressure within a vacuum chamber or other pressurized container.\u003c\/p\u003e\u003cp\u003eUnlike most ported pressure sensors, this one uses I2C, it's \u003cem\u003ereally easy\u003c\/em\u003e 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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eWe'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\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cul\u003e\n\u003cli\u003eUses I2C address 0x18\u003c\/li\u003e\n\u003cli\u003e0 to 25 absolute PSI measurement range\u003c\/li\u003e\n\u003cli\u003eApp notes and datasheets for Honeywell MPR series micro pressure sensors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProduct Dimensions: 17.8mm x 16.7mm x 7.5mm \/ 0.7\" x 0.7\" x 0.3\" \u003c\/p\u003e\n\u003cp\u003eProduct Weight: 1.1g \/ 0.0oz \u003c\/p\u003e\n\u003c\/div\u003e \u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":53697531117844,"sku":"sor1787257924829","price":21.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0946\/9486\/7220\/files\/adafruit-mprls-ported-pressure-sensor-breakout---0-to-25-psi_1.jpg?v=1787257929","url":"https:\/\/regalwearstore.shop\/products\/adafruit-mprls-ported-pressure-sensor-breakout-0-to-25-psi","provider":"My Store","version":"1.0","type":"link"}
