Finally a real-world practical use for a Pi!  This it the first one I
have ever seen.

This is a great idea as our experience with commercial environmental
monitoring devices has been less than stellar.  I'd be very happy to
having something that just chugged poll results into syslog; if it could
generate an SNMP trap that would be extra awesome.
