BMP180, and \u003ca href=\"\/en-eu\/products\/adafruit-bmp280-i2c-or-spi-barometric-pressure-altitude-sensor\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eBMP280\u003c\/a\u003e... now we've got the next generation, the Adafruit BMP388 Precision Barometric Pressure sensor.\u003c\/p\u003e\n\u003cp\u003eAs you would expect, this sensor is similar to its earlier versions but \u003cem\u003eeven better\u003c\/em\u003e. The BMP388 has better precision than ever, which makes it excellent for environmental sensing or as a \u003cstrong\u003eprecision altimeter\u003c\/strong\u003e. It can even be used in either I2C and SPI configurations.\u003c\/p\u003e\n\u003cp\u003eThe BMP3xx is the next-generation of sensors from Bosch and is the upgrade to the BMP280 - with a low altitude noise as low as 0.1m and the same fast conversion time. And like the previous BMP280, you can use I2C or SPI. For simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI.\u003c\/p\u003e\n\u003cp\u003eThis sensor has a relative accuracy of 8 Pascals, which translates to about ± 0.5 meters of altitude (compare to the BMP280's 12 Pascal\/ ±1 meter). The datasheet sort of implies they intend this sensor to be used for drones and quadcopters, to keep altitude stable, but you could also use this for wearables or any project that wants to track height-above-sea-level. Note that for absolute height you'll still need to enter in the barometric pressure at sea level if the weather changes, but that's true of every altimeter sensor that uses pressure. You can also measure temperature with ±0.5°C accuracy.\u003c\/p\u003e\n\u003cp\u003eNice sensor right? So Adafruit made it easy for you to get right into your next project. The surface-mount sensor is soldered onto a PCB and comes with a 3.3V regulator and level shifting so you can use it with a 3V or 5V logic microcontroller without worry. \u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_BMP3XX\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eCheck out the Arduino library to get data out in under 10 minutes!\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eShould you wish to avoid soldering, it now also includes \u003ca href=\"\/en-eu\/collections\/stemma-qt\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eStemma QT\u003c\/a\u003e connectors (\u003ca href=\"\/en-eu\/collections\/qwiic\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSparkFun Qwiic\u003c\/a\u003e compatible).

Additionally, this sensor breakout may come with black or tan STEMMA QT connectors. They work the same!\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAs of February 23, 2021\u003c\/strong\u003e, Adafruit have updated this sensor to be STEMMA QT compatible - that means there's now an easy way to plug-and-play this sensor without any soldering! The physical shape has changed, but the pinout is identical to the non-QT earlier version.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":13588964376659,"sku":"ADA3966","price":10.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/3966-10.jpg?v=1672928773","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/adafruit-bmp388-precision-barometric-pressure-and-altimeter","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
