XH2.54/XF2510 3P 12V Car Anti-theft Vibration Sensor, GY166
1. Output current: 100mA (MAX)
2. Sensitivity: -105dB
3. Quiescent current: 6mA
4. Rated operating Voltage: 12V
5. Operating voltage: 5V (MIN)
6. Cable type: 1m shielded cable
7. Adhesive backing for easy mounting
8. Piezoelectric and spring sensing components for high accuracy and stable operation
9. Clockwise rotation increases sensitivity, counterclockwise rotation decreases sensitivity
10. Vibration sensing system composed of a buzzer and contact spring, offering high sensitivity, speed, and performance
11. Internally, a piezoelectric ceramic component and spring weight structure detects vibration signals, which are amplified and output via an op amp such as the LM358
Pin description:
1. The blue wire is the signal output via the 358 op amp. It is high when there is no vibration (IO port pull-up resistor) and low when there is vibration.
2. Red wire: +12V power supply.
3. Black wire: ground.
Pin definition:
1. Blue wire: signal output. Each vibration detected generates a pull-down signal for one cycle, allowing for interfacing with a microcontroller.
2. Black wire: ground.
3. Red wire: positive power supply (5-15V DC).
