lm_sensors (Linux-monitoring sensors), a free open source software-tool for Linux, provides tools and drivers for monitoring temperatures, voltage, and fans. It also monitors chassis intrusion detection.

decode-dimms.pl decodes and prints information on any RAM memory module with SPD information in the computer.

It contains a library called libsensors with an API that applications can use. It contains a daemon called sensord which supports RRD.

lm-sensors 3 requires Linux kernel 2.6.5 (released in 2004) and later.

lm-sensors 2 requires Linux kernel 2.4 (released in 2001) and later.

Software such as GKrellM, KSensors, xsensors, Net-SNMP make use of lm-sensors or can make use of lm-sensors.

KSensors - an lm_sensors frontend for KDE.
