Limits can be 38set through the Overtemperature Shutdown register and Hysteresis register. The 39sensor is accurate to 0.5 degree over the range of -25 to +85 C, and to 1.0 40degree from -40 to +125 C. Resolution of the sensor is 0.0625 degree. The 41operating temperature has a minimum of -55 C and a maximum of +150 C. 42 43The TMP102 has a programmable update rate that can select between 8, 4, 1, and 440.25 Hz. 45 46The TMP110 and TMP113 are software compatible with TMP102, but have different 47accuracy (maximum error) specifications. The TMP110 has an accuracy (maximum error) 48of 1.0 degree, TMP113 has an accuracy (maximum error) of 0.3 degree, while TMP102 49has an accuracy (maximum error) of 2.0 degree. 50 51sysfs-Interface 52--------------- 53 54The following list includes the sysfs attributes that the driver provides, their 55permissions and a short description: 56 57=============================== ======= =========================================== 58Name Perm Description 59=============================== ======= =========================================== 60temp1_input: RO Temperature input 61temp1_label: RO Descriptive name for the sensor 62temp1_max: RW Maximum temperature 63temp1_max_hyst: RW Maximum hysteresis temperature 64update_interval RW Update conversions interval in milliseconds 65=============================== ======= =========================================== 66
