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.

Specifications:

Supply voltage (Vcc): 5V

Quiescent current: 4ma typ. (power LED on)

Max. current drain: 7ma (both LED on)

Dimensions: 32 mm x 14mm

Vcc:  +5V Positive supply

GND: Negative supply

Do:    Digital output
