+.Sh NAME
+.Nm lisa
+.Nd STMicroelectronics LIS331DL MEMS motion sensor
+.Sh SYNOPSIS
+.Cd "lisa* at iic?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the ST LIS331DL
+3-axis digital output accelerometer.
+A total of 3 sensors are provided, one for each axis
+(X, Y and Z).
+Each reading from LIS331DL is represented by an
+8-bit 2's complement number.
+.Pp
+Sensor values are made available through the
+.Dv HW_SENSORS
+.Xr sysctl 3
+interface,
+and can be monitored with the
+.Xr systat 1
+.Ar sensors
+view,
+.Xr sensorsd 8
+and
+.Xr sysctl 8
+.Ar hw.sensors .
