Limits can be +set through the Overtemperature Shutdown register and Hysteresis register. The +sensor is accurate to 0.5 degree 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. + +The TMP102 has a programmable update rate that can select between 8, 4, 1, and +0.25 Hz. + +The TMP110 and TMP113 are software compatible with TMP102, but have different +accuracy (maximum error) specifications. The TMP110 has an accuracy (maximum error) +of 1.0 degree, TMP113 has an accuracy (maximum error) of 0.3 degree, while TMP102 +has an accuracy (maximum error) of 2.0 degree. + +sysfs-Interface +--------------- + +The following list includes the sysfs attributes that the driver provides, their +permissions and a short description: + +=============================== ======= =========================================== +Name Perm Description +=============================== ======= =========================================== +temp1_input: RO Temperature input +temp1_label: RO Descriptive name for the sensor +temp1_max: RW Maximum temperature +temp1_max_hyst: RW Maximum hysteresis temperature +update_interval RW Update conversions interval in milliseconds +=============================== ======= =========================================== |
