2.4.6 Pressure Sensor

The BMP280 device is a digital pressure sensor for measuring barometric pressure conditions (see [6]). The BMP280 can also be used to determine altitude. Some other features of the sensor include the following:

  • Wide pressure range of 300 hPa to 1100 hPa
  • High accuracy
  • Low current consumption of 2.7 µA @ 1 Hz sampling rate
  • I2C and SPI serial communication interface
