.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module is a simplified interface to the HidTEMPer thermometers created 
by PCSensor. It hides any problems recognizing the correct objects to 
initialize and the dependency on Device::USB. Use of the connected 
thermometers can be done by either creating a array of objects if 
multiple devices are connected, or the function \fBdevice()\fR if 
only one device is present.
.PP
One example of its usage can be found in the Linux Journal August 2010, 
\&\*(L"Cool Projects edition\*(R" page 32\-34.
