The motorcycle anti-theft alarm is introduced in this article, it uses the private displacement sensor and has the features of high sensitivity, good reliability, low false alarm rate and easy to make. The principle of the circuit This motorcycle anti-theft alarm circuit is composed of the integrated vibration displacement sensor (it is composed of the solid acceleration detection sensor and the control integrated circuit) 1Cl, the power supply circuit and the alarm circuit, the circuit is as shown in figure 7-87. The power supply circuit is composed of the three-port integrated voltage regulator IC2, the filter capacitor C2. The +12V voltage is from the motorcycle battery. The +12V voltage is stabilized by IC2 to become the +6V voltage.
