LMENV(4)                  OpenBSD Programmer's Manual                 LMENV(4)

NAME
     lmenv - National Semiconductor LM87 temperature, voltage, and fan sensor

SYNOPSIS
     lmenv* at iic?

DESCRIPTION
     The lmenv driver provides support for the National Semiconductor LM87,
     National Semiconductor LM81, Analog Devices ADM9240, and Dallas Semicon-
     ductor 1780 temperature sensors.  The sensor possesses a collection of
     sensor values which are made available through the sysctl(8) interface:

           $ sysctl hw.sensors.lmenv0
           hw.sensors.lmenv0.temp0=-128.00 degC (External)
           hw.sensors.lmenv0.temp1=29.00 degC (Internal)
           hw.sensors.lmenv0.fan0=3220 RPM
           hw.sensors.lmenv0.volt0=2.62 V DC (+2.5Vin)
           hw.sensors.lmenv0.volt1=1.49 V DC (Vccp)
           hw.sensors.lmenv0.volt2=3.28 V DC (+Vcc)
           hw.sensors.lmenv0.volt3=5.03 V DC (+5Vin/Vcc)
           hw.sensors.lmenv0.volt4=12.00 V DC (+12Vin)
           hw.sensors.lmenv0.volt5=1.20 V DC (Vccp)
