Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
This driver implements support for the National Semiconductor LM92
|
||
|
|
temperature sensor.
|
||
|
|
|
||
|
|
Each LM92 temperature sensor supports a single temperature sensor. There are
|
||
|
|
alarms for high, low, and critical thresholds. There's also an hysteresis to
|
||
|
|
control the thresholds for resetting alarms.
|
||
|
|
|
||
|
|
Support was added later for the LM76 and Maxim MAX6633/MAX6634/MAX6635,
|
||
|
|
which are mostly compatible. They have not all been tested, so you
|
||
|
|
may need to use the force parameter.
