    Term Accuarcy in Datasheets

    Hello everyone,
    I have a question regarding the Bosch data sheets: In those the accuracy of sensors (e.g. BME280) is indicated. However, there seems to be no information on the standard deviation of a sensor. Is there a relationship between the accuracy you specify and the standard deviation of the signal? For example accuracy = 3*std? Or can the standard deviation be read from your data sheets in another way?

    Kind regards.

    Hi CiMatt,

    In the BME280 datasheet minimum/maximum values of drifts, offsets and temperature coefficients are three-sigma values over lifetime,  you can find this information in  page 8 of the BME280.

    for you reference the typical value are in general 1-sigma.

    Thanks
