[vc_row][vc_column width=”1/1″][vc_tour][vc_tab title=”Introduction” tab_id=”1393912008-1-22″][vc_column_text]The Vibration sensors use a spring based sensor. When there is vibration, it will output a digital signal.

There are three pins: power supply, ground, and output signal.

int sensorPin = A0;
int ledPin = 13;
int sensorValue = 0;

void setup() {
  pinMode(ledPin, OUTPUT);  
  Serial.begin(115200);
}

void loop() {
  sensorValue = analogRead(sensorPin); 
  Serial.println(sensorValue);  
  digitalWrite(ledPin, HIGH);  
  delay(100);          
  digitalWrite(ledPin, LOW);   
  delay(100);                  
}

When the module do not have shacking the value is larger than 360, if the value is less than 100, that means the vibration sensor is open. According to the above data, we can define that when the value is less than 80, the module is connecting; When the value is larger than 300, the module is disconnection. That can eliminate switching shacking problem.
