This chip has two power modes: one-shot (chip takes one measurement and
|
||
|
|
then shuts itself down) and continuous (chip takes continuous
|
||
|
|
measurements). The one-shot mode is more power-friendly but the
|
||
|
|
continuous mode may be more reliable. If this property is specified
|
||
|
|
the continuous mode will be used instead of the default one-shot one for
|
||
|
|
raw reads.
