|

help
|
||||
In Hold mode the measurement is started and the sensor blocks the
|
||||
master by clock stretching until the measurement is finished. Thus,
|
||||
in this mode, both the I2C bus and the processor are blocked for the
|
||||
entire measurement duration, which can be up to 85 ms for temperature
|
||||
measurement and up to 29 ms for humidity measurement, depending on the
|
||||
resolution. Therefore, the no-hold mode should be used, where the
|
||||
measurement is started and a timer is used to fetch the results.
|
||||
This way neither the I2C bus nor the processor are blocked for the
|
||||
duration of the measurement. Furthermore, the hold mode requires that
|
||||
the MCU supports clock stretching.
