.Sh NAME
.Nm lmenv
.Nd National Semiconductor LM81, LM87, and compatible hardware monitors
.Sh SYNOPSIS
.Cd "lmenv0 at iic0 addr 0x2c: ADM9240 rev 2"
.Sh DESCRIPTION
The
.Nm
driver provides support for the
.Tn National Semiconductor
LM87,
.Tn National Semiconductor
LM81,
.Tn Analog Devices
ADM9240, and
.Tn Dallas Semiconductor
DS1780 iicbus hardware monitors.
Sensor values are reported through the
.Xr envstat 8
interface.
.Pp
The
.Nm
supports the following voltage, temperature, and fan speed sensors:
.Bl -column "+5Vin/Vcc" "Temperature" -offset indent
.It Sy "Sensor" Ta "Type"
.It Li "+2.5Vin" Ta "Volts DC"
.It Li "Vccp1" Ta "Volts DC"
.It Li "+Vcc" Ta "Volts DC"
.It Li "+5Vin/Vcc" Ta "Volts DC"
.It Li "+12Vin" Ta "Volts DC"
.It Li "Vccp2" Ta "Volts DC"
.It Li "External" Ta "Temperature"
.It Li "Internal" Ta "Temperature"
.It Li "FAN1" Ta "Speed"
.It Li "FAN2" Ta "Speed"
.El
On the LM87 monitor, AIN1 and AIN2 Volts DC sensors may replace either,
or both of the FAN1 and FAN2 speed sensors, respectively.

.Nm
driver first appeared in
.Ox 3.9 .
.Nx
support was added in
