lm_sensors

lm_sensors is an open source command-line software that provides essential drivers for monitoring the temperatures, voltages, and fans of Linux systems.

lm_sensors also contains tools for sensor hardware identification and I2C bus probing.

What is new in version 3.3.2:

• Support for many sub-features was added to libsensors and sensors.
• Sysfs detection was fixed to keep working after a sysfs implementation change in upcoming kernels.
• Printing of power sensors was improved.
• Memory leaks were fixed in sensord.
• Detection of new chips was added to sensors-detect.

What is new in version 3.3.1:

• Detection of new devices was added to sensors-detect.

What is new in version 3.3.0:

• Support for chassis intrusion detection and humidity sensors was added, as well as many new attributes for existing sensor types.

What is new in version 3.1.1:

• This is a maintenance release, collecting 4 months of random fixes. All users of 3.1.0 are encouraged to upgrade.

What is new in version 3.1.0:

• Completely reworked sensors-detect. Support for Linux 2.4 was dropped, devices probe order was reverted (integrated sensors first, I2C/SMBus chips last), bus driver names are retrieved from sysfs, bus number prediction was fixed, modules we loaded ourselves are unloaded. The script is significantly smaller, and smarter.
• Improvements to libsensors. Circular dependencies in the configuration file are detected and dealt with, and more importantly, support for multiple configuration files was added. This is an important step in the direction of automatic lm-sensors configuration. Also some performance and memory usage improvements. Support for instantaneous power sensors and current sensors.
• The format of /etc/sysconfig/lm_sensors was changed. The new format is easier to edit, which will ease integration with external tools. Use the included script sysconfig-lm_sensors-convert to convert from the old to the new format.
• New default sensors.conf file. Much lighter, with only always-correct statements. Big performance boost, and hopefully less confusion for the user.
• And as usual, random fixes to all tools.
