This doorbell solve the trouble and inconvenience of the use of ordinary doorbell skillfully, the problems include that the door have to be holed (especially iron door), and have the button switch fixed installed. Accordingly putting an end to the phenomenon such as the intended breakage of others, etc. It’s innovative and practical with the popularize value. This paper design use the MCU AT89C1051 as the central control chip, process the vibrated sensor signal with the use of integrated chip LM324, simulate output the audio signal as “Ding Dong!" sound, and make the use of LM386 to amplify the output signal and drive the loudspeaker.Furthermore, this design can also use voice integrated chip, using the levels from SCM output pins to control audio output. We may also produce all-purpose voice ...
