54 time of issue of the bulk read command (not the current temperature).
58 ``conv_time`` is used to get current conversion time (read), and
59 adjust it (write). A temperature conversion time depends on the device type and
60 it's current resolution. Default conversion time is set by the driver according
61 to the device datasheet. A conversion time for many original device clones
62 deviate from datasheet specs. There are three options: 1) manually set the
63 correct conversion time by writing a value in milliseconds to ``conv_time``; 2)
64 auto measure and set a conversion time by writing ``1`` to
67 the default conversion time write ``0`` to ``conv_time``.
