Product Description:
The BMP280 is a digital barometric pressure sensor with a relative accuracy of ±0.12 hPa (equivalent to ±1 meter). The sensor's power consumption is only 2.7μA. The BMP280 uses a highly compact 8-pin metal-lid LGA package. It includes both pressure and temperature measurement functions and supports both SPI and IIC communication interfaces. Compared to the previous generation BMP180, the BMP280 offers significantly improved accuracy, making it suitable for low-cost multi-rotor flight controllers.
Note: The I2C address is 0x76, which is different from the default 0x77 used by most other sensors. You will need to manually change the address in the Adafruit_BMP280.h file to: #define BMP280_ADDRESS (0x76).
