Using it
Frontends
There are many front-ends for lm sensors:
Hands On
3. sensord
This daemon resides in /etc/init.d/. You need to restart it to get your sensor modules loaded and be able to gather information form them. Type:
/etc/init.d/lm_sensors restart
Thus it will try to stop and start the deamon or just start it if it was down.
That's all. Now you will be able to use your favorite application to display your sensor's data.
