2Pcs Universal Automobile Motorcycle Car Vibration Sensor with Anti-Theft Alarm Function and Adjustable Induction for Enhanced Security

2Pcs Universal Automobile Motorcycle Car Vibration Sensor with Anti-Theft Alarm Function and Adjustable Induction for Enhanced Security 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 for low cost and practical use in modern security. 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 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. 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) 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. 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). Color: Black Material: ABS+Metal Package Contents: 2 x Sensor Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
