The sensor possesses a collection of sensor values which are made available through the .Xr sysctl 8 interface.
p The ADC date unit is "VDC"(DC voltage) and the value is signed. Because the Analog-Digital conversion cycle of the device is faster than the sensor framework update cycle, the driver keeps maximum/minimum/average values of each cycle as independent sensors.
p The device has a unique serial number, indicated in the description part of the sensor value. .Sh SEE ALSO .Xr intro 4 , .Xr uhidev 4 , .Xr sensorsd 8 , .Xr sysctl 8 .Rs .%T Toradex Web Page .%U http://developer.toradex.com/hardware-resources/usb-sensors-and-peripherals .Re .Sh HISTORY The .Nm device driver first appeared in .Ox 5.3 . .Sh AUTHORS .An -nosplit The .Nm driver was written by .An Yojiro UO Aq Mt yuo@nui.org .
