lm_sensors (Linux-monitoring sensors) is a free open-source software-tool for Linux that provides tools and drivers for monitoring temperatures, voltage, humidity, and fans. It can also detect chassis intrusions.[citation needed]

## Issues

During 2001/2004, the lm_sensors package was not recommended for use on IBM ThinkPads due to potential EEPROM corruption issues on some models when aggressively probing for I2C devices.[2][3][4] This has since been dealt with, and the separate README file dedicated to ThinkPads was removed in 2007.[5]

In 2013, the `sensors-detect` command of lm-sensors began disrupting the gamma correction settings of some laptop display screens. This occurs while it is probing the I2C/SMBus adapters for connected hardware monitoring devices. Probing of these devices was disabled by default.[6] [7][8][9]
