Product description
Module features:
1、Using the W-420 normally closed type vibration sensor produced by our company.
2、Comparator output, clean signal, good waveform, strong driving ability, more than 15mA
3、Operating voltage 3.3V-5V
4、Output form ：Digital switching output (0 and 1)
5, with fixed bolt holes, easy to install
6, small board PCB size: 3.2cm x 1.4cm
7, the use of wide voltage LM393 comparator
Module use instructions:
1, the product does not vibrate, the vibration switch is closed conduction state, the output output low level, green indicator light;
2, when the product vibration, the vibration switch is instantly disconnected, the output output high level, the green indicator light is not lit;
3, the output can be directly connected to the microcontroller, through the microcontroller to detect the high and low levels, thereby detecting whether the environment has vibration, play a role in alarm!
