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 ±6 Pascals at room temperature, which translates to about ±50 centimeters of altitude (compare to the BMP280's ±12 Pascal\/±1 meter and BMP388's ±8 Pascal\/±0.5 meter). The typical absolute accuracy is ±30Pa or about 2.5 meters. Check the datasheet for how temperature and altitude can affect the absolute\/relative accuracy.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe BMP580 is software\/firmware compatible with the \u003ca rel=\"noopener\" href=\"\/products\/adafruit-bmp581-i2c-or-spi-temperature-and-pressure-sensor-stemma-qt\" target=\"_blank\"\u003eBMP581\u003c\/a\u003e but has less accurate\/precision measurements.\u003c\/strong\u003e\u003cspan\u003e It's also less expensive! So pick this when cost is more important than accuracy.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe 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 we made it easy for you to get right into your next project.
