    BMX160 reading accuracy

    BMX160 reading accuracy

    Hi

    I’m currently using a BMX160 shuttle board on an esp8266 microcontroller, however the readings I am obtaining as an output from the bmx are only whole numbers, no decimals
    E.g 10 instead of 9.81. Does this have something to do with the library I am using, or is the BMX160 sensor not capable of high accuracy values?

    Hello Calvin111,

    It seems to have something to do with the data conversion on your MCU platform.

    To how many decimal places can then sensor be accurate to then?

    Hello Calvin111,

     

    For accelerometer of BMX160, output data format is LSB/g. It is not floating point number, so without decimal places.

    For example of 8G range, it could be convert to (x/4096.0)g、(y/4096.0)g、(z/4096.0)g.

    Hi

     

    So just to confirm then, the bmx160 sensor is only capeable of returning whole numbers (integers)?

    Or is it capable of returning floats aswell?
