12V DC Motorcycle Car Alarm System Vibration Sensor Alarm Anti-theft Device

Description: 12V DC Motorcycle Car Alarm System Vibration Sensor Alarm Anti-theft Device Description: This product uses a vibration sensing system consisting of a buzzer and a contact spring, which is characterized by high sensitivity, fastness and high performance. It is widely used in car anti-theft and other security products. It has become the first choice for low cost and practical use in modern security. The internal piezoelectric ceramic sheet and spring weight structure are used to detect the vibration signal, and the amplifier signal is amplified by the LM358 and output control signals. It has the advantages of low cost, high sensitivity, stable and reliable operation, and large adjustable range of vibration detection. On the anti-theft system of steam and motorcycle cars, 80% of the vehicle alarms use such sensors. The sensor uses SMT chip technology inside, and the imported components are assembled. The sensor can also be combined with single-chip microcomputer, wireless transmitter module, wired alarm, etc. It is used in combination and has a wide range of uses. Parameter: Material: ABS + Electronics Output current: ≤100mA (maximum load current) Sensitivity: -105dB Quiescent current: ≤6mA Rated working voltage: 12V Minimum operating voltage: >5V Trigger pole number: unipolar trigger output Interface mode: XH2.54 or 2510 three wire interfaces (interface socket is 2.54 3P common models, if you need 2510 3P interface, you can contact us) Trigger mode: negative trigger to ground or positive 12V trigger Working voltage: DC10V-16V Sensitivity: the twist can be debugged Indication mode: LED light red light indication Description: 1. The blue line is the signal output output by the 358 op amp. If the signal is not vibrated, it is high (the IO port should be pulled up), and if the signal is vibrated, it is low (signal to ground). 2. Red line power: +12V 3. The black line is the ground line Notes: If the output is connected to the high level, it needs to add a resistor of 100 ohms or less. If you want to drive the wireless transmitter module, you can not replace the resistor. The red and black wires are connected to the positive and negative power input of the module. The number (DC alarm horn) is preferably an external relay control to avoid large current damage to the sensor internal components (for reference).
