NAME
     acpitz - ACPI thermal zone

SYNOPSIS
     acpitz* at acpi?

DESCRIPTION
     The acpitz driver supports ACPI Thermal Zones.  Temperature information
     is available through this driver as a sensor which is updated every 10
     seconds or, if the implementation supports it, via an event.  If the tem-
     perature exceeds the `critical' temperature threshold, the system will be
     shut down and powered off.  The sensor provided by acpitz can be moni-
     tored using sysctl(8) or sensorsd(8).

HISTORY
     The acpitz driver first appeared in OpenBSD 3.8.
