Hi, Do my calculations look correct using the corresponding calibration and Temperature/Pressure/Humidity readings? Thanks! ... View more

Hi, So I think I have figured out the problem, the calibration values were not being treated as signed (the ones that should be). So could someone verify these results for me please? (The Raw Calibration Values are the same as above).

Hi, Do my settings/data look correct? Could it be a faulty sensor, or am I missing something? Thanks ... View more

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) Regards, ...
