Motorcycle Car General Vibration Induction Vibration Alarm StableReliable Description: OOTDTY Features: brand new and high quality Uses a vibration detection system that consists of a and a contact spring. Characterized by high sensitivity, speed and high performance. It is widely used in car anti-theft and other security products. The internal piezoelectric ceramic sheet and the spring weight structure are used to detect the vibration The amplifier is amplified by the lm358 and output control signals. Low cost, high sensitivity, stable and reliable operation, large adjustable of vibration detection. In the anti-theft system for steam for cars and motorcycles, 80% of vehicle alarms use these sensors. The uses smt chip technology inside, and the imported components are assembled. Can also be combined with a single chip microcomputer, wireless transmitter module, alarm, etc. It is used in combination and has a wide of uses. Leading wire description: 1. the blue line is the output by the 358 op amplifier. If the is not vibrated, it is high (the port must be pulled up), and if the is vibrated, it is low to earth) 2. power: + 12 v 3. the black line is the earth line Notice: If the output is at the high level, it needs to add a resistor of 100 ohms or less. If you want to the wireless transmitter module, you cannot replace the resistor. The red and black wires are to the positive and negative power input of the module.
