This object reports the live current temperature reading from a specific sensor on the module. An admin polls this to catch overheating -- from a clogged fan filter, a failed fan, or a hot equipment room -- before the card automatically shuts itself down for thermal protection, which would otherwise look like an unexplained outage. For example, a steady reading of 42 degrees C is unremarkable, but a climb to 78 degrees C on the same sensor within an hour signals an imminent thermal fault worth investigating immediately.
