Car Motorcycle General Vibration Inductive Vibration Sensor Alarm Anti-theft Device High Sensitivity, Stable and Reliable Operat -- 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 anti-theft cars and other security products. It has become the first choice of low-cost and practical applications 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 steam cars and motorcycles, 80% of vehicle alarms use such sensors. The sensor uses SMT chip technology inside, and imported components are assembled. The sensor can also be connected to a 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: le; 100mA (maximum load current) Sensitivity: -105dB Quiescent current: le; 6mA Rated working voltage: 12V Minimum working 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, ) Trigger mode: negative trigger to ground or positive trigger 12V Operating voltage: DC10V-16V Sensitivity: twist can be debugged Indication mode: LED traffic light red light Description: 1. The blue line is the output of the output signal through the op-amp 358. 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: +12V3. The black line is the ground line Notes: If the output is connected to high level, it must add a resistor of 100 ohms or less. If you want to drive the wireless transmitter module, you cannot replace the resistor. The red and black wires are connected to the positive and negative power inputs of the module. The number (DC alarm horn) is preferably external relay control to avoid high voltage current damaging the internal components of the sensor (for reference).
