No, but a plethora of other temperature sensors (my current favorite:
Itwatchdogs Weathergoose)

The name is mostly irrelevant.  The target is everything.

Here's a sample.  To make this work, I used a LoadMIBs: line that
included the mib file (and any pre-requisite mibs)

# Created by 
# /usr/bin/cfgmaker --ifref=name --nointerfaces
--host-template=probe.template --subdir=central/HOSTNAME
--output=/var/mrtg/cfg/central/foo-probe.cfg
public at foo-probe.example.com::2:1:1:1


### Global Config Options

#  for UNIX
# WorkDir: /home/http/mrtg

#  or for NT
# WorkDir: c:\mrtgdata

### Global Defaults

#  to get bits instead of bytes and graphs growing to the right
# Options[_]: growright, bits

EnableIPv6: no
