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 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
  1. int Din = 2;    
  2. int Dout = 13;    
  3. int LEDStatus = HIGH;    
  4. int Reading;    
  5. int Previous = LOW;    
  6. long DTime = 0;    
  7. long Dbounce = 50;    
  8. void setup()    
  9. {    
  10.     pinMode(Din, INPUT);    
  11.     digitalWrite(Din, HIGH);    
  12.     pinMode(Dout, OUTPUT);    
  13. }    
  14. void loop()    
  15. {    
  16.     int ReadingState;    
  17.     Reading = digitalRead(Din);    
  18.     if (Reading != Previous)    
  19.     {    
  20.         DTime = millis();    
  21.     }    
  22.     if ((millis() - DTime) > Dbounce)    
  23.     {    
  24.         ReadingState = Reading;    
  25.         if (ReadingState == HIGH) LEDStatus = LOW;    
  26.         else LEDStatus = HIGH;    
  27.     }    
  28.     digitalWrite(Dout, LEDStatus);    
  29.     Previous = Reading;    
  30. }   
Explanation
 
It will explain the earth level where we have a fix.
 
When an earthquake occurs, LED will ON.
 
When it does not occur, LED will OFF.
 
Output
