lm_sensors is a free Linux program for monitoring various sensors . lm_sensors reads temperature , voltage and fan speed values via SMBus or I²C from the registers in the sensor.

The program contains a program library ( libsensors ) with a programming interface and the daemon sensord .

Sample output

$ sensors
nouveau-pci-0100
Adapter: PCI adapter
temp1:            N/A  (high = +95.0°C, hyst =  +3.0°C)
                       (crit = +105.0°C, hyst =  +5.0°C)
                       (emerg = +135.0°C, hyst =  +5.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +54.0°C  (high = +84.0°C, crit = +100.0°C)
Core 0:         +52.0°C  (high = +84.0°C, crit = +100.0°C)
Core 1:         +54.0°C  (high = +84.0°C, crit = +100.0°C)

configuration

The sensors-detect command line application can be used to search for sensors embedded in the hardware. Some may require additional kernel modules . Often no sensors can be read out on notebooks, since the power management is not taken over by the operating system but by the ACPI .

Public perception

The lm_sensors program has already been mentioned in several books internationally, including in German Networks with Linux: High availability, security and performance ... and the magazines Linux-Magazin , c't -Magazin, ADMIN-Magazin and PC-Welt .
