Car Motorcycle Universal Anti Theft Sensor Adjustable Car and Motorcycle Detection Vibration Sensor L27 Alarm Anti-theft Device -- Car Motorcycle Universal Anti-Theft Sensor Adjustable Car and Motorcycle Vibration Detection Sensor L27 Alarm Anti-theft Device Description: This product uses a vibration detection system consisting of a buzzer and a spring, which is characterized by high sensitivity, durability and high efficiency. 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 LM358 and the output control signals. It has the advantages of low cost, high sensitivity, stable and reliable operation and large adjustable vibration detection range. In the anti-theft system of cars and motorcycles, 80% of the vehicle's alarm uses such oacute;w sensors. The sensor uses SMT chip technology inside, and 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 applications. Parameter: Material: ABS + electronics Output current: 100mA (maximum load current) Sensitivity: -105dB Quiescent current: 6mA Rated operating voltage: 12V Minimum operating voltage: 5V Trigger pole number: unipolar trigger output Interface mode: XH2.54 or 2510 interfaces three wires (interface socket is 2.54 popular 3P models, if you need 2510 3P interface, ) Trigger mode: negative trigger to ground or positive trigger 12V Working voltage: DC10V-16V Sensitivity: twist can be debugged Indication mode : LED light indication red light Description: 1. Blue line is the output signal by op 358 amplifier. If the signal is not vibrating, it is high (the IO port should be pulled up), and if the signal is vibrating, it is low (signal to ground). 2. Red line power: +12V 3. Black line is the ground line Notes: If the output is connected to high level, it must add a resistor with a power of 100 ohms or less. If you want to drive the transmitter module wireless, you cannot replace the resistor. The red and black wires are connected to the positive and negative power supply of the module. The number (DC alarm horn) is preferably external control of the relay to avoid high voltage damage to the internal component of the sensor (for reference).
