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
Semiconductor 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)
