But, how much air is in the atmosphere, bearing down on us?\u003c\/p\u003e\u003cp\u003eThis absolute pressure sensor, \u003cstrong\u003eST LPS25HB\u003c\/strong\u003e can quickly and easily measure this air pressure, useful when you want to know about the weather (are we in a low pressure or high pressure system?) or to determine altitude, as the air thins out the higher we get above sea level. For example, at sea level, the official pressure level is \u003cstrong\u003e1013.25 hPa. \u003c\/strong\u003eYou can use this sensor to measure the current pressure where you are right now, to compare.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003eLPS25\u003c\/strong\u003e has a wide measurement range of \u003cstrong\u003e260-1260 hPa \u003c\/strong\u003ewith 24-bit pressure data measurements that can be read up to \u003cstrong\u003e25 times a second (Hz)\u003c\/strong\u003e, you can be confident that you always have an up to date and precise measurement. It's pretty dang accurate too, with the ability to measure\u003cstrong\u003e within 0.2 hPa\u003c\/strong\u003e after calibration (± 1 hPa before calibration).\u003c\/p\u003e\u003cp\u003eThese days, helpful little sensors like the LPS25 are often quite little and tend to come in surface-mount packages that make them tricky to use with breadboards. With that in mind, we've taken the LPS25 and put it on a breakout board with level shifting circuitry and a voltage regulator. This means that not only can you use it with a breadboard, but you can use it with a wide range of devices that have either a \u003cstrong\u003e3.3V logic level\u003c\/strong\u003e, like a Raspberry Pi or CircuitPython compatible Metro M4 Express, \u003cstrong\u003eor with a 5V logic level\u003c\/strong\u003e device like a Metro 328 or Arduino Uno.\u003c\/p\u003e\u003cp\u003eFurthermore, we've included SparkFun Qwiic compatible STEMMA QT connectors for the I2C bus so you don't even need to solder! All you need to do is plug in a compatible cable, wire it up to your device using one of our wiring diagrams and you're ready to write some code to start reporting measurements. \u003cstrong\u003eQT Cable is not included\u003c\/strong\u003e, but we have a variety in the shop. \u003c\/p\u003e\u003cp\u003eTo make the coding easier, we've written \u003cstrong\u003elibraries for Arduino\u003c\/strong\u003e and \u003cstrong\u003eCircuitPython or Python\u003c\/strong\u003e along with accompanying \u003cstrong\u003eexample code\u003c\/strong\u003e, so all you have to do is gather your supplies and follow our instructions and you can know just how much air is sloshing around in your vicinity.\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\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":48624074260698,"sku":"kyp1789681821454","price":8.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/adafruit-lps25-pressure-sensor---stemma-qt-qwiic-lps25hb_1.jpg?v=1789681826","url":"https:\/\/memoryfoamwear.shop\/products\/adafruit-lps25-pressure-sensor-stemma-qt-qwiic-lps25hb","provider":"My Store","version":"1.0","type":"link"}
