Vibration Sensor

Use SW18015 Vibration sensor

This vibration sensor use the switch SW-18015P, high sensitivity, generally used to detect ambient vibration strength
When the vibration reach the set threshold, the the DO port output high, and when the external shock or vibration does not exceed the set threshold, the module D0 output low;
Outputs D0 can be directly connected with the MCU, which can detect high and low TTL from module, and thus to detect the vibration of the environment;
Output D0 can directly drive our relay module, which can form a shock switch;
