Arduino Vibration Switch Module KY-002 Keyes allows detection of shock and vibration. The KY-002 Vibration Switch Module consists of a conductive vibration spring and a 10k resistor, it will react to shock and vibration by closing the circuit.
Specifications:
Operating Voltage: 5V
Dimensions 18.5mm x 15mm [0.728in x 0.591in]
Connection Diagram
Connect the Power line (middle) and ground (-) to +5 and GND respectively. Connect signal (S) to pin 3 on the Arduino.
Example Code
The following Arduino sketch produces a shock flasher. Pin 13 (LED) on the Arduino will flash when KY-002 detects movement. Pin 3 is used as input from KY-002.
int Led =13; // define the LED Pin
int shock =3 // define the sensor Pin
int val; // define a numeric variable val
voidsetup(){pinMode(Led,OUTPUT); // LED pin as output
pinMode(shock,INPUT); // input from KY-002 sensor
}voidloop(){
val =digitalRead(shock); // read the value from KY-002
if(val ==HIGH){// when sensor detects shock, LED flashes
digitalWrite(Led,LOW);}else{digitalWrite(Led,HIGH);}}
