Source: InternetPublisher:兰博 Keywords: Electric bicycle anti-theft alarm Updated: 2020/11/30
Shown is an electric bicycle anti-theft alarm lock circuit. This circuit uses a vibration sensor device. When the car is moved, the vibration
sensor will send a signal to the base of the VT1 transistor. After being amplified by VT1, the amplified signal is added to IC1 The ① pin is output by the ④ pin after being processed by IC1
, and drives the buzzer through VI2 to sound a warning sound to attract the attention of the car owner.
