| 19 | ----------- |
| 20 | |
| 21 | The Texas Instruments TMP102 implements one temperature sensor. Limits can be |
| 22 | set through the Overtemperature Shutdown register and Hysteresis register. The |
| Jean Delvare | cff37c9 | 2010-05-27 19:58:57 +0200 | [diff] [blame] | 23 | sensor is accurate to 0.5 degree over the range of -25 to +85 C, and to 1.0 |
| 24 | degree from -40 to +125 C. Resolution of the sensor is 0.0625 degree. The |
| Steven King | beb1b6b | 2010-05-27 19:58:56 +0200 | [diff] [blame] | 25 | operating temperature has a minimum of -55 C and a maximum of +150 C. |
| 26 | |
| 27 | The TMP102 has a programmable update rate that can select between 8, 4, 1, and |
| 28 | 0.5 Hz. (Currently the driver only supports the default of 4 Hz). |
| 29 | |
| 30 | The driver provides the common sysfs-interface for temperatures (see |
