Before getting started, you will have to install lm-sensors first.       

• Install the sensors. Simply go to terminal and copy-paste following.

sudo apt-get install lm-sensors

• Create file called mkdev.sh, and paste in the following

         #!/bin/bash

         # Here you can set several defaults.

         # The number of devices to create (max: 256)
         NUMBER=32

         # The owner and group of the devices
         OUSER=root
         OGROUP=root
         # The mode of the devices
         MODE=600

         # This script doesn't need to be run if devfs is used
         if [ -r /proc/mounts ] ; then
         if grep -q "/dev devfs" /proc/mounts ; then
         echo "You do not need to run this script as your system uses devfs."
         exit;
         fi
         fi

         i=0;

         while [ $i -lt $NUMBER ] ; do
         echo /dev/i2c-$i 
         mknod -m $MODE /dev/i2c-$i c 89 $i || exit
         chown "$OUSER:$OGROUP" /dev/i2c-$i || exit
         i=$[$i + 1]
         done
         #end of file

• Make this file executable, then run it

        sudo chmod +x mkdev.sh 
        sudo ./mkdev.sh

• Now detect sensors, and answer "y" to all questions.

        sudo sensors-detect

• To load the manual modules, type

        sudo /etc/init.d/module-init-tools

•  Load the modules into kernel with

        sudo sensors -s

• And check the output

        sudo sensors
