lmenv —
National Semiconductor LM87 temperature, voltage, and fan
sensor
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)
The lmenv driver first appeared in
OpenBSD 3.9.
