Description
|
|
-----------
|
|
|
|
The Texas Instruments TMP108 implements one temperature sensor. An alert pin
|
|
can be set when temperatures exceed minimum or maximum values plus or minus a
|
|
hysteresis value. (This driver does not support interrupts for the alert pin,
|
|
and the device runs in comparator mode.)
|
|
|
|
The sensor is accurate to 0.75C over the range of -25 to +85 C, and to 1.0
|
|
degree from -40 to +125 C. Resolution of the sensor is 0.0625 degree. The
|
|
operating temperature has a minimum of -55 C and a maximum of +150 C.
|
|
Hysteresis values can be set to 0, 1, 2, or 4C.
|
|
|
|
The TMP108 has a programmable update rate that can select between 8, 4, 1, and
|
|
0.5 Hz.
|
|
|
|
By default the TMP108 reads the temperature continuously. To conserve power,
|
|
the TMP108 has a one-shot mode where the device is normally shut-down. When a
|
|
one shot is requested the temperature is read, the result can be retrieved,
|
|
and then the device is shut down automatically. (This driver only supports
|
|
continuous mode.)
|
|
|
|
The driver provides the common sysfs-interface for temperatures (see
|
|
Documentation/hwmon/sysfs-interface.rst under Temperatures).
