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:

           hw.sensors.0=lmenv0, +2.5Vin, volts_dc, 2.62 V
           hw.sensors.1=lmenv0, Vccp1, volts_dc, 1.49 V
           hw.sensors.2=lmenv0, +Vcc, volts_dc, 3.28 V
           hw.sensors.3=lmenv0, +5Vin/Vcc, volts_dc, 5.03 V
           hw.sensors.4=lmenv0, +12Vin, volts_dc, 12.00 V
           hw.sensors.5=lmenv0, Vccp2, volts_dc, 1.20 V
           hw.sensors.6=lmenv0, Ext. Temp., temp, -128.00 degC / -198.40 degF
           hw.sensors.7=lmenv0, Int. Temp., temp, 29.00 degC / 84.20 degF
           hw.sensors.8=lmenv0, FAN1, fanrpm, 3220 RPM
