Which is consistent with the outputs I see on my Ubuntu 13.10. Line 846: 846 int sensors_read_sysfs_attr(const sensors_chip_name *name,Ĩ47 const sensors_subfeature *subfeature,Īccording to the sysfs documentation, the sensors information is stored under /sys/class/hwmon with different directory for each chip. In /sys/class/thermal I have trying to browse lm-sensors source code in search for how it retrieves temperature, to no avail so far, however I am close. No /sys/class/thermal/thermal_zone0/ directory sensors application however can display a temperature on my machine. And is simple reading a text file only possibility or maybe I can query the kernel using system call or signal?Ĭontent of my folder /proc/acpi/ is just event wakeup How can I get CPU temperature in C or C++ on Linux Ubuntu 12.10 without call to sensors? I can of course just read it from file, however I cannot find where it is stored in 12.10.

There are many questions similar to this but I haven't found solution there.
