      This sensing module uses a normally opened 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.
