The Adafruit LPS28 (LPS28DFW) Pressure Sensor is unique in that it can handle a much higher range of pressures: almost every other sensor we've encountered tops out at about 1260 hPa. That means they're totally fine for measuring altitude for most human endeavours, we tend to stay above sea level. However, for some scientific or deep-water uses, 1260 will not cut it! That's why we're happy to stock a sensor that can go down to \u003ca href=\"https:\/\/www.st.com\/en\/mems-and-sensors\/lps28dfw.html\" title=\"4060 hPa Product overview\"\u003e4060 hPa\u003c\/a\u003e - that's as low as -43,000 feet below sea level in air or 40 meters underwater.\u003c\/p\u003e \u003cp\u003eWe covered the \u003ca href=\"https:\/\/blog.adafruit.com\/2022\/08\/04\/eye-on-npi-st-lps28dfw-dual-full-scale-absolute-digital-output-barometer-eyeonnpi-digikey-st_world-digikey-adafruit\/\"\u003eLPS28DFW sensor on our EYE ON NPI video segment\u003c\/a\u003e, and liked it so much that we turned it into a product!\u003c\/p\u003e \u003cp\u003eThat makes this a good sensor for use with underwater devices or robots, as it can tell your depth from the pressure readings. Of course, it's also still a great sensor for altitude sensing out of the water: with a 24-bit sensor and the ability to discern absolute pressure changes of ±0.5 hPa at the highest quality readings, good for less than 1 centimetre of altitude. (Like all pressure sensors, the actual altitude above sea level depends on the day's pressure at sea level) Or, if you need speed, it can do up to 200 samples per second, without filtering and averaging.\u003c\/p\u003e \u003cp\u003eThe sensor comes with a little metal port, so you could connect a thin tubing to it for measuring pressure far from where it is soldered. The sensor element within the package has potting gel good for up to 10,000 hPa of pressure and protection against some harsh chemicals - \u003ca href=\"https:\/\/www.st.com\/en\/mems-and-sensors\/lps28dfw.html\" title=\"Datasheet\"\u003echeck the datasheet\u003c\/a\u003e for more information to make sure you can use it to measure the pressure of the liquid or gas you need.\u003c\/p\u003e \u003cp\u003eTo make life easier when working with this fancy sensor, we've taken the LPS28 and put it onto a breakout PCB along with support circuitry to let you use this little wonder with 3.3V (\u003ca href=\"\/nl\/collections\/adafruit-feather\" title=\"Adafruit Feather\"\u003eFeather\u003c\/a\u003e\/\u003ca href=\"\/nl\/collections\/raspberry-pi-store\"\u003eRaspberry Pi\u003c\/a\u003e) or 5V (\u003ca href=\"\/nl\/collections\/arduino-store\" title=\"Arduino Store\"\u003eArduino\u003c\/a\u003e\/ Metro328) logic levels. Additionally, since it speaks I2C you can easily connect it up with two wires (plus power and ground!). We've even included SparkFun qwiic compatible STEMMA QT connectors for the I2C bus so you don't even need to solder! Just wire up to your favourite micro and you can use our CircuitPython\/Python or Arduino drivers to easily interface with the LPS28 and make approximate approximations of proximity in no time! \u003cstrong\u003eQT Cable is NOT included\u003c\/strong\u003e, but we have a \u003ca href=\"\/nl\/search?q=Stemma+QT+cable\u0026amp;narrow_by=\u0026amp;sort_by=relevency\u0026amp;page=1\" title=\"Stemma QT cable\"\u003evariety in the shop\u003c\/a\u003e\u003c\/p\u003e \u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"\/\/www.youtube.com\/embed\/HCvOiXD9pJs?si=pQkcr1YCEUXp5T0Q\u0026amp;start=43\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen=\"allowfullscreen\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e \u003ch2\u003eSpecifications\u003c\/h2\u003e \u003cp\u003e\u003cstrong\u003eLPS28DFW Specifications:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eDual full-scale absolute pressure with water-resistant package\u003cbr\u003e– Mode 1: 260 ~ 1260 hPa\u003cbr\u003e– Mode 2: 260 ~ 4060 hPa\u003c\/li\u003e \u003cli\u003eAbsolute pressure accuracy: 0.5 hPa\u003c\/li\u003e \u003cli\u003eLow-pressure sensor noise: 0.32 Pa\u003c\/li\u003e \u003cli\u003eEmbedded temperature compensation\u003c\/li\u003e \u003cli\u003e24-bit pressure data output\u003c\/li\u003e \u003cli\u003eODR from 1 Hz to 200 Hz\u003c\/li\u003e \u003cli\u003eI²C or MIPI I3CSM interface\u003c\/li\u003e \u003cli\u003eEmbedded FIFO\u003c\/li\u003e \u003cli\u003eInterrupt functions: data-ready, FIFO flags, pressure thresholds\u003c\/li\u003e \u003cli\u003eEasily sealed package with O-ring\u003c\/li\u003e \u003cli\u003eDefault I2C address 0x5C, can be set to 0x5D\u003c\/li\u003e \u003cli\u003eDimensions: 25.4mm x 17.8mm x 4.8mm\u003c\/li\u003e \u003cli\u003e\u003cspan\u003eWeight: 1.8g\u003c\/span\u003e\u003c\/li\u003e \u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":50847135138065,"sku":"ADA6067","price":11.8,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/6285\/6209\/files\/adafruit-lps28-lps28dfw-pressure-sensor-stemma-qt-qwiic-adafruit-ada6067-72089350046081.jpg?v=1735207524","url":"https:\/\/abcd3032.myshopify.com\/nl\/products\/adafruit-lps28-lps28dfw-pressure-sensor-stemma-qt-qwiic","provider":"Tayyab Zak","version":"1.0","type":"link"}
