The batter monitoring system is a modified home plate for baseball including a sensor unit to detect whether or not the bat crosses the plate as a hitter swings at a pitched ball and also when a runner crosses the plate. After the pitch, a green light is illuminated to indicate that the batter swung the bat or a red light is illuminated if the batter did not swing the bat. Each player would wear a transmitter which the sensor would detect as it crossed the plate, illuminating the lights and sounding a buzzer to indicate when the device is detected crossing the plate. This allows the umpire to watch the ball coming into the baseman's glove and determine whether the ball arrived before or after he heard the buzzer. The sensor, lights, control unit, and buzzer would be built into the plate, and the plate would be recessed into the ground so that its appearance does not differ from that of a conventional home plate.
