This sensing module uses a normally closed mechanical vibration
sensor to active a very sensitive comparator IC to process the vibration
signal. When vibration is detected, the IC output will change from high
voltage to low voltage and will turn on its output indicator LED.
Applications:
Earth quake alert, vibration alarm for security, motor vehicle bump
alarm, machine abnormal operation alert, etc.
