If you want something that does not depend on a desktop:
Have a look at lm-sensors . From the description:
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.
This package contains programs to help you set up and read data from
From their project page:
- Unattended high-end server, router or other mission-critical machine automated monitoring. Easily create a cron job to query the status of your hardware and email you in the event of a problem before it becomes critical. That way, you can be alerted within seconds of a failing critical component such as a power supply, fan, other cooling mechanism, or even detect if the case has been opened.
- Embedded systems running Linux. These can use this package to monitor voltages, temperatures, fan speeds, etc. using off-the-shelf components and utilizing a range of bus interfaces (e.g. ISA, SMBus, I2C or SPI).
- More generally, data acquisition. Easily measure various types of data (rotational speeds, voltages, temperatures, etc.) using cheap off-the-shelf parts. Very useful for systems automation (in the home, workshop, weather station, you name it).
lm-sensors has a daemon, called sensord, that uses RRDtool for 'data logging and graphing system for time series data'. So it includes graphics like this that can be shown through a webserver:

To install the sensord daemon you will likely have to install the sensord package.
Example from my notebook:
The config file for this is located at
lm-sensors is sort of the basic of any temperature measuring. Desktop items are more than likely to get their information from this package.
An example If you want something that depends on a desktop
- motherboard and CPU sensors (requires lm-sensors to be installed).
- NVidia GPUs
- Hard Disk Drives (requires hddtemp to be installed).
- Fan speed (again, requires lm-sensors to be installed).
Installation by adding a PPA:
sudo add-apt-repository ppa:jfi/ppa
sudo apt-get update && sudo apt-get install psensor
(Oneiric will have psensor included)
