Have you looked at these? POE and small.
I haven't tried them myself, but they look interesting and versatile
(SNMP and HTTP).

Not bad in comparison to a lot of other choices. Base unit is $210 and
probes are $54, but the base unit is small enough that you could deploy
it almost anywhere.
Poseiden 3265 is also promising, but I wasn't able to find direct
pricing after some quick searching around.
There's probably a hack you could do with Rasberry Pi for < $100 too.
also, sensaphone is not cheap, but you can run the sensors over any
cat-5 house wiring that you have hundreds of feet away. 8 built-in ports
and remote units available. IMS-4000 1RU base server is ~$2k.
temperature/humidity probes extra. These are more for alarming as the
sensaphone has all kinds of triggers, alerts, etc.

We're having some issues with temperature control in our office.
Depending on the day different staff say it's too cold or too warm.
There appears to be some big temperature variances across the building
(it's not just personal preferences, but I'm sure that's part of it).
The HVAC people say that they don't see any issues when they visit the
office. With answers like that, I think they use to be sysadmins!
I'd like to place temperature sensors across our office and trend their
data via snmp. My initial thought was to get some server room sensors
and put them in strategic locations throughout the building and move
them around every few weeks. But, that's a lot of work for imprecise
data. If possible, I'd like to have one central temperature sensor in my
network closet and rj45 sensor probes in as many as 50 rooms via the
building's wiring infrastructure. Has anyone done anything like this or
know of a temperature sensor setup that can accommodate (or scale) to
this size? Most of the systems I'm familiar with only accept a few
probes and don't scale at all.
