Feature:
Is used to the effect of different vibrations, theft alarm system,trigger intelligent car, earthquake warning, motorcycle alarm etc.
This module is compared with the normally open type vibration sensor module,Vibration trigger for a long time, the relay module can drive.

Module properties:
1. The company usually produces closed vibration sensor Type SW-420.
2. The comparative output, signal clean, good wave shape, the driving ability is strong, more than 15 mA.
3. The operating voltage from 3.3V to 5V.
4. Expenses: digital switching exit (0 and 1).
5 .. has a solid back hole, comfortable installation.
6. Small circuit board PCB size:. 32cm x 14mm
7. Use the LM393 wide voltage comparative

Module application:
1. Product no vibrations, vibration switch is closed to condition, the output connection issued low level, the green light is glowed;
2. Product vibration, the vibration switch immediately interruption, output of the exit high level, the green light is not bright;
3. Output can be connected directly to the microcontroller, by one-chip microcomputer to record the high and low levels, to recognize whether there is a vibration environment, call the police.

Package included:
6 x SW-420 alarm motion sensor modules vibration switch
