Easy Vibration Shock module(SE025)
1 Introduction
This module is a shock switch module, and if it can detect a jolt ,it output low level
signal. It’ similar with the Vibration Shock module (SE053), the difference is that this
module has one indicator light, which would be on when this module’s voltage signal
is changed. And, this module has integrated 3-pin terminal, which can be simply and
tidily connected with Arduino sensor expansion board, like the following picture:
Specification
Operation voltage: 5V
With 3-Pin Jumper
Size:25*15mm
Weight: 6g
2 Pinout
Pin
Description
OUT
If the sensor detect a jolt, this pin
output low level signal

3.Example
This example show you how to use this module, connection as below, and upload
the sketch, open the serial monitor session, see how it will go~
Example code :
******Code begin******
int shockPin = 10; // Use Pin 10 as our Input
int shockVal = HIGH; // This is where we record our shock measurement
boolean bAlarm = false;
unsigned long lastShockTime; // Record the time that we measured a shock
int shockAlarmTime = 250; // Number of milli seconds to keep the shock
alarm high
void setup ()
{
Serial.begin(9600);
pinMode (shockPin, INPUT) ; // input from the KY-002
}
void loop ()

{
shockVal = digitalRead (shockPin) ; // read the value from our sensor
if (shockVal == LOW) // If we're in an alarm state
{
lastShockTime = millis(); // record the time of the shock
if (!bAlarm){
Serial.println("IDUINO Shock module");
bAlarm = true;
}
}
else
{
if( (millis()-lastShockTime) > shockAlarmTime && bAlarm){
Serial.println("no alarm");
bAlarm = false;
}
}
}
******Code End******
