That's the exact thermometer we are talking about most often. It doesn't have to hang up high on the wall. It should actually sit right on the substrate. I prop mine up in one corner of the cool side of the tank and run the probe over to the warm side and tuck it under the warm-side hide. Some people use a little strip of sticky-sided velcro to attach it to the side of the enclosure. I've done both, and find that propping it up works just fine and has no risk of the snake being exposed to sticky stuff.


(The snake WILL move it around sometimes, but it's no big deal to just put it back where it belongs.)
