Yo All!
I am surprised that the TEMPer and TEMPerHUM have not been mentioned
yet. They are cheap reliable USB temperature sensors. The TEMPerHUM
adds a humidity sensor.
I have several TEMPer's running to log room temp around NTP servers.
The basic TEMPer reads to 0.1°F is only $9:

I can't speak to its accuracy, but it tracks well with my OXO's frequency
shifts.
There is the double sensor TEMPER for about $19:

I do NOT recommend this one. The external temp will not match the internal
temp. When I put an IR camera on it I found the external temp sensor
self heats in free ait by several degrees F.
I have not tried the TEMPerHum. It adds a humidity sensor and is $20:

I'm kind of curious about their "UI".. hold CapsLock? how does this
device manifest itself to the host computer? I saw a mention of HID, so
it is emulating a keyboard?
(which, by the way, is the current strategy for infecting computers with
USB thumb drives you leave in the parking lot of your victim.. it works
as a thumb drive, except it also looks for other interesting traffic and
injects a payload at that time, as if you were on a keyboard..)

From what I can tell, many different Chinese companies make TEMPer's so
YMMV. But hard to go wrong for $9.
