Lm-sensors is a hardware health monitoring package for Linux. It allows you to access information from temperature, voltage, and fan speed sensors. It works with most newer systems.

Step 1.  Install lm-sensors using apt-get.

Run the following command:

apt-get install lm-sensors

Step 2. Detect your sensors using the following command:

sensors-detect

Answer yes to all questions.(recomended)

Step 3. View your sensors runing the following:

sensors

The output will be something like this:
