Earthquake Detector Using Arduino

Abstract: Earthquake is an inevitable phenomenon that happens quickly and cannot be prevented, but can be warned. An accelerometer ADXL335 sensor is used to detect pre-earthquake vibrations. When a vibration occurs, the accelerometer detects and converts the equivalent ADC value. These digital values are then read by the microcontroller Arduino. Arduino then compares these values with the current values.If the Arduino detects that the standard value is greater than the threshold, it will beep and display a message on the 16x2 LCD indicating the alarm status and the LED will light up at the same time. SMS notification messages are sent to the relevant mobile phone number using the GSM module. Both sensors are used for fire detection and gas leaks in the building can be detected using a combination of flame and smoke. If an SMS notification is detected, it will be sent to the corresponding mobile number.
