1. Omnidirectional, any Angle can be activated

2. This switch is suitable for small current tripping circuit
3. Operating voltage: 3,3 v ~ 5v
4. Digital switch output (0 and 1)
5. Dimensions: 0.94x0.59x0.35 inches (2,4x1, 5x0.9 cm)
6. Component model: sw-18015p

This module consists of a conductive spring, a 10k resistor, and 3 male header pins. Knocking or shaking the module will cause the spring to momentarily close the circuit.

Operating Voltage 5V
Board Dimensions 18.5mm x 15mm [0.728in x 0.591in]


Connect the module signal pin (S) to pin 3 on the Arduino.

Then connect the module’s power pin (middle) and ground (-) to +5V and GND on the Arduino respectively.

S Pin 3
middle +5V
Arduino KY-002 connection diagram


The following Arduino sketch produces a shock flasher. The LED on Arduino pin 13 will flash when the KY-002 is knocked or shaked. Pin 3 receives the signal from the module.

int Led = 13; // define the LED Pin
int shock = 3 // define the sensor Pin 
int val; // define a numeric variable val 
void setup () {
	pinMode (Led, OUTPUT); // LED pin as output  
	pinMode (shock, INPUT); // input from KY-002 sensor
void loop () {
	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);
