- Used for various vibration triggering functions, reporting burglary alarm, smart car, earthquake alarm, motorcycle alarm, etc.
- Compared with the normally open vibration sensor module, this module can trigger the vibration for a longer time and can drive the relay module.
Module features:
1. Using SW-420 normally closed type vibration sensor.
2. Comparator output- clean signal- good waveform- strong driving ability- >15mA.
3. Working voltage: 3.3V ~ 5V.
4. Output format: digital switching output (0 and 1).
5. With bolt holes for easy installation.
6. Small board, PCB dimensions: 3.2 x 1.4 cm.
7. Using a wide voltage LM393 comparator.
Note:
If the module does not vibrate- the vibration switch was closed on state- output of low output- the green indicator light.
The product vibrates- vibration switch momentary disconnect- output is driven high- the green light does not shine.
The output can be directly connected with the microcontroller- which to detect high and low level- so as to detect whether the environment exist vibration- play a role in the alarm.
