TMP275: Reading temp data with shorter time period than the conversion time

Tool/software:

Hi team

Is it possible to read temp data with shorter time period than the conversion time?

If they read temp data via I2C every the short period, e.g. 10ms, that is shorter than conversion period(27.5ms), they can read data twice at least. In this case, can they read same temp data in these two readings?

Regards,

    Hello Noriyuki,

    The conversion time is the length of time it takes for the sensor to make a new temperature measurement. If you read earlier than the conversion time, then you will read the same temperature result.
