Using lm-sensors to get temperature

Question

I've done an app to communicate with an arduino board that shows the info i send in a LCD. The problem is that i want to send the CPU temp, i know the best is use lm-sensors (i'm using linux) but don't know how, it doesn't have any example, so, does somebody know how to use it or where i can get an example?

Answer 1

If the lm_sensors modules are already loaded, the temperatures should be accessible in files from sysfs (for example: /sys/class/hwmon/hwmon0/device/temp1_input) that you can read with standard C/C++ file functions.
