Assuming that you are borrowing power from the hall board, then yes. The hall's +5 wire (typically red) will go to the LM35's +Vs, and the hall's ground (typically black) goes to the LM35's GND. VOUT
from the LM35 is a variable voltage output, and this should go straight to the (+) terminal of a voltmeter (or similar) with no pullup. Ideally, the voltmeter's (-) terminal will go back to the hall ground wire, both for safety and to minimize the opportunity for ground offset skewing your readings.
ps. i'm curious about your avatar. what's the story about it?
Well, it's a giant chicken dressed as Boba Fett from the Star Wars movies. Seems pretty self-explanatory to me.
I've been pretty heavily involved in the Mazda Miata (MX-5) aftermarket for a number of years, principally with regards to forced induction, ECUs and engine tuning. Back in 2007, a specific manufacturer of supercharger kits started making some false and unsupportable statements about a specific ignition-control device which he was offering, which a user on one of the Miata forums posted a link to. (It should be noted that a state of inter-forum cold war has also existed for many years between the forum in which said posting occurred and the rival MiataTurbo.net form, on which I'm a moderator. I routinely frequent both forums, however.)
An epic thread ensued, with forum members allying themselves both with and against the vendor in question, mostly reflective of the long-standing and nearly religious debate which has long waged between fans of supercharging vs. fans of turbocharging. The vendor in question started digging himself into a hole and throwing out a lot of obfuscation and pseudo-science in an effort to confuse the populace and thus draw attention away from the matter at hand. At some point during the debate, I used the "walks like a duck, quacks like a duck"
analogy. Mr. pseudo-science then said (and I'm quoting directly) that "a duck, chicken and goos are all the same. Although the feces is completely different."

At that point, the whole chicken / duck / goose concept virtually became a meme within the forum community. And at the suggestion of a user at MiataTurbo.net, I decided to adopt a poultry theme for my avatars, as both an inside joke and a persistent jab. Since then, I've used chickens and ducks exclusively as my avatar theme, both on the Miata forums and elsewhere, as it's quite memorable.
The fact that Ernie the Giant Chicken is wearing a Boba Fett costume in the current avatar is of no particular significance. I saw it in an episode of the TV show Family Guy, thought it was funny, and took a screen capture of it.
The concept of "average" requires that 50% of the population be below it.
