The KY-002 is a shock and vibration sensor. It consists of a conductive outer shell, which closes the contact with an internal spring in case of vibrations and thus emits a signal.

This is an example program that lights up an LED when a signal is detected at the sensor.
The modules KY-011, KY-016 or KY-029 can, for example, be used as LEDs, for example.
int Led = 13 ;// declaration of the LED output pin
int Sensor = 10 ;// Declaration of the sensor input pin
int val; // Temporary variable
void setup ()
{
pinMode (Led, OUTPUT) ; // Initialize output pin
pinMode (Sensor, INPUT) ; // Initialize sensor pin
digitalWrite(Sensor, HIGH) ; // Activate internal pull-up resistor
}
void loop ()
{
val = digitalRead (Sensor) ; // The current signal at the sensor is read out
if (val == HIGH) // If a signal could be detected, the LED is switched on.
{
digitalWrite (Led, LOW);
}
else
{
digitalWrite (Led, HIGH);
}
}

This is an example program that prints a console output when as signal is detected at the sensor.
# Required modules are imported and set up
import RPi.GPIO as GPIO
