Installing the lm-sensors tool makes it easy to read sensor information and monitor hardware temperatures, including those of the CPU and hard drive. Here are the general steps to install lm-sensors on a Linux system:

1. Open the terminal (command line interface).
2. Check if lm-sensors is already installed on your system by running the following command: sudo sensors-detect --version. If you see a message indicating that the sensors-detect command does not exist, it means lm-sensors is not installed on your system.
3. Install lm-sensors using your package manager. Different Linux distributions use different package managers, so choose the appropriate command for your distribution:
   • For Debian or Ubuntu systems: sudo apt-get install lm-sensors
   • For CentOS or RHEL systems: sudo yum install lm_sensors
   • For Arch Linux systems: sudo pacman -S lm_sensors
4. After installation is complete, run the following command to configure it: sudo sensors-detect. This command will scan your system and detect supported sensor devices.
5. During the configuration process, you will be prompted with a series of questions. You can simply press the Enter key to accept the default settings or configure it according to your needs. Note: When asked “Do you want to add these lines automatically to /etc/modules? (yes/NO)”, select “yes” to ensure the sensor modules load automatically at system startup.
6. Once configuration is complete, run the following command to update sensor information: sudo sensors-detect --auto.
7. Now you can run the following command to view sensor information and temperatures: sensors. The output will display the actual temperatures of various sensor devices in your system.

With this, you have successfully installed lm-sensors and configured the sensors. You can run the sensors command anytime to check hardware temperatures. Please remember to run the relevant commands with administrative privileges (using sudo).
