ABSTRACT: In this paper, an intelligent electronic timer is designed by using the voice control module,
infrared module, high precision clock module and STC89C52 SCM which is regarded as the core. The switch
display of the time, date and temperature can be achieved through a digital tape. In particular, the sound of a
starter’s gun shot can be used as a signal to start the stopwatch timing, and ending the timer with the signal of
