Hi,
Thanks for your inquiry.
BMP280 pressure sensor and temperature sensor oversampling is as shown below in register 0xF4.
For example, BMP280 pressure sensor oversampling setting is bit 4, 3, 2 in register 0xF4.
If these three bits are 0b000, then it means the pressure sensor is skipped without any measurement.
If these three bits are 0b001, then it means the pressure sensor makes one single measurement and puts the measurement in the data registers.
If these three bits are 0b010, then it means the pressure sensor makes two measurements, averages them and puts the averaged value in the data registers.
If these three bits are 0b011, then it means the pressure sensor makes four measurements, averages them and puts the averaged value in the data registers.
So on and so on. The higher the oversampling value, the cleaner the data will be and of course the higher the current consumption as the trade-off.
Thanks.
