is there a way to create an execution every time a specific variable/value changes?

[fallow sedge]

i need to know if i can create an execution from the change of a value, so if the float value changes from (2.46) to (7.23) it will create an execution so that the rotator gizmo will update without overloading my cpu (before i was making it update every 0.1 seconds, which is killing my cpu, and i need it to be optimised)

get event receiver and config it to receive "{Variable name} Changed", this will fire exec when the variable changed expect if it changed to the same value
