These chips implements one local +and up to one (TMP421), up to two (TMP422) or up to three (TMP423) +remote sensors. Temperature is measured in degrees Celsius. The chips +are wired over I2C/SMBus and specified over a temperature range of +-40=B0C to +125=B0C. Resolution for both the local and remote channels is +0.0625=B0C. + +The chips supports only temperature measurement and exports these +values via following sysfs-interface: + +temp[1-4]_input +temp[2-4]_fault _______________________________________________ lm-sensors mailing list lm-sensors@lm-sensors.org http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
