LM-Sensors (Linux-Meters) is a free and open-source application that provides a way to monitor and control the temperature, fan speed, and other vital information about the hardware components of a computer system. It can be used to monitor hardware components such as CPUs, GPUs, hard disks, and RAM, as well as temperature, fan speed, and voltage. LM-Sensors uses a set of tools and drivers to access data from hardware sensors in the computer, and then displays the data in an easy-to-read format. The application also has the capability to alert the user when certain thresholds are reached. LM-Sensors is a powerful tool for system administrators, allowing them to monitor and manage their systems more effectively.
