Limits can be +set through the Overtemperature Shutdown register and Hysteresis register. The +sensor is accurate to 0.5 degrees over the range of -25 to +85 C, and to 1.0 +degrees 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. + +The TMP102 has a programmable update rate that can select between 8, 4, 1, and +0.5 Hz. (Currently the driver only supports the default of 4 Hz). + +The driver provides the common sysfs-interface for temperatures (see +/Documentation/hwmon/sysfs-interface under Temperatures). + |
