An electronic whistle system pertains to an electronically activated handheld whistle with a transmitter and receiver modules, for use at various sports games, is disclosed. The transmitter module is configured to send a serialized pulse signal to the receiver module for regulating the start and stop of the game clock. The transmitter module comprises an optical sensor on the opposite side of a vane, which occludes an optical sensor beam when the whistle is blown. A microcontroller sends a serialized pulse signal from the transmitter module to the receiver module. The receiver module intercepts the received signal on the detection of correct serial number, the receiver module will send a STOP pulse to the game clock via a cable. The electronic whistle system is designed to dramatically reduce the errors in the timing aspect of various games.
