ABSTRACT:
A sensing home plate, structurally assembled from a home plate main body, and a sensing device disposed therein. The sensing device is assembled from a power supply circuit, a signal transmitting circuit, a fine tuning circuit, a signal receiving circuit, and an acousto-optic circuit. The signal transmitting circuit transmits signals, and forms a sensing area on the upper side of the home plate main body. When a baseball passes through or contacts the sensing area causing interference therewith, then a signal is received by the signal receiving circuit, and the acousto-optic circuit emits sound and light as a means to indicate such. The present invention can thus be used in the sport of baseball to accurately determine whether or not the ball pitched by the pitcher is a strike (good pitch) or ball (bad pitch), thereby assisting the chief umpire in making decisions, and reducing judgmental errors.
