Simple Earthquake Sensor Detection And Vibration Mode By Arduino Mega 2560

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.
