For the reading part, it might be worth looking at lmsensors source code http://dl.lm-sensors.org/lm-sensors/snapshots/

Unless you particularly want to write it yourself lmsensors and something like GKrellM will do it.

or
Code:
man proc
cat /proc/acpi/fan/fan0
cat /proc/acpi/thermalzone/zone1/foo
depending on what this is for might also work ?

the directories /proc/acpi/fan/ and /proc/acpi/thermalzone/ are empty they do not have fan0 and zone1/foo in it...
