BME280 Data to test Calculations

[Badger]

Hello,

Could someone please send me some the raw calibration values, and the raw register values for the Temperature/Pressure/Humidity for the BME280.

With also the correct calculated Temperature/Pressure/Humidity readings?

I would like to test my calculations as I think my pressure calculations are incorrect.

Thanks!

Thanks for the link. I had seen (and used) the excel form already. What I needed was the Raw (Hex) data which is returned from the BME280, unfortunatley the sheet does not have this.

The issue I have is that the BME280 returns a high pressure reading, the form also shows this so it is not my calculations. Is the sensor faulty?

The temperature is correct, and humidity I don't have anything to check against.

The Raw values are:

Calibration:

0x6C, 0x6E, 0x77, 0x66, 0x32, 0x00, 0xA8, 0x92, 0x27, 0xD5, 0xD0,
0x0B, 0x6F, 0x18, 0xCA, 0xFF, 0xF9, 0xFF, 0xAC, 0x26, 0x0A, 0xD8,
0xBD, 0x10, 0x4B, 0x65, 0x01, 0x00, 0x14, 0x0B, 0x00, 0x1E

Temp/Press?Humidity:

0x55, 0x33, 0x80, 0x81, 0x7F, 0xB0, 0x79, 0x13

Calculations are:

+24.44°C
1148.38hPa
54.17%rH

Settings are:

0xF5 = 0b10101000  ' Config Setting (1000ms Standby, IIR Filter @ 4)
0xF2 = 0b00000010  ' Humidity Setting (x2 Oversampling)
0xF4 = 0b01001011 ' Temp/Pres Settings (x2 Oversampling, Normal Mode)

Hi,

Do my settings/data look correct?

Could it be a faulty sensor, or am I missing something?

Thanks

Hi Badger,

The data that you provided does not specify which value corresponds to which calibration register. I could not decode the calibration data.
