Introduction

In my last article I explained about finding weather conditions using Arduino Mega 2560. Now In this article I will explain about simple earthquake sensor detection and vibration mode with Arduino Mega 2560.

Parts Of Lists

Arduino UNO/MEGA/PRO
1x Vibration Tilt Switch
1x LED
1x 220 k Resistor
1x 10k Resistor.

Connection

Connection from the Vibration Tilt Switch to Arduino Mega 2560:

Figure 1: Vibration Tilt Switch

Sensor Board
Vcc------->5V.
Gnd------->Gnd.
Din-------->02.
Connection From Led To ArduinoMega2560:
Postive pin(Dout)-------->13
Negative pin------->Gnd.

Programming

int Din = 2;
int Dout = 13;
int LEDStatus = HIGH;
int Reading;
int Previous = LOW;
long DTime = 0;
long Dbounce = 50;
void setup()
{
pinMode(Din, INPUT);
digitalWrite(Din, HIGH);
pinMode(Dout, OUTPUT);
}
void loop()
{
int ReadingState;
Reading = digitalRead(Din);
if (Reading != Previous)
{
DTime = millis();
}
if ((millis() - DTime) > Dbounce)
{
ReadingState = Reading;
if (ReadingState == HIGH) LEDStatus = LOW;
else LEDStatus = HIGH;
}
digitalWrite(Dout, LEDStatus);
Previous = Reading;
}

Explanation

It will explain the earth level where we have fix.

When earthquake occurs, LED will ON.

When it does not occur, LED will OFF.
