Extract code: 1234
use:
Used for various vibration triggers, reporting the alarm, smart car, earthquake alarm, motorcycle alarm, etc.
Compared with the constant open vibration sensor module, this module has a longer vibration trigger, which can drive the relay module

Module characteristics:
1. Use the SW-420 normally closed vibration sensor produced by the company.
2. The output of the comparator, the signal is clean, the waveform is good, and the driver capacity is strong, more than 15mA
3. Work voltage 3.3V-5V
4. Output form: Digital switching output (0 and 1)
5. There are fixed bolt holes for easy installation
6. Small board PCB size: 3.2cm x 1.4cm
7. Use width voltage LM393 comparator

Module use instructions:

1. When the product is not vibrating, the vibration switch is closed in a closed lead, the output end outputs low levels, and the green indicator lights are on;

2. When the product is vibrating, the vibration switch is disconnected instantly, the output end outputs high level, and the green indicator is not on;

3. The output end can be directly connected to the single -chip microcomputer, and the high and low levels are detected by a single -chip machine. Therefore, the environment is to vibrate and play a role in alarm.
