LSM303D temperature format

Hello,

I got good results reading accelerometer data but the temperature register is about 36 (decimal), the datasheet mentions 8LSB/Â°C, 36/8 = 4.5Â°C, this is quite cold 😉

Room temp is 24Â°C, the other sensors located near the LSM are indicating 28Â°C.

What is the good conversion factor?

Hi,

I see there has been no replies to your post for the past 2 years.

Unfortunately

the temperature sensor can be used only to measure temperature variations. It isn't suitable to return absolute temperatures measures. The value represents difference respect to a reference not specified value.

Best regards
