1. A surgical stapler comprising:
(a) a body assembly;
(b) a shaft assembly that extends distally from the body assembly;
(c) a stapling head assembly disposed at a distal end of the shaft assembly, wherein the stapling head assembly is operable to drive a plurality of staples into tissue, wherein the stapling head assembly comprises a closure shaft that is selectively movable longitudinally; and
(d) an anvil configured to form the staples, wherein the anvil is selectively coupleable with and actuatable by the closure shaft, wherein the anvil comprises:
(i) one or more sensors each configured to detect a parameter associated with at least one of closure or firing of the end effector;
(ii) a processor configured to receive signals from the one or more sensors, wherein the signals are indicative of the parameter detected by the one or more sensors;
