Developed an ESP32-based earthquake detection system as part of an Internet of Things (IoT) course, utilizing an MPU6050 accelerometer with an OLED display, LEDs, and a buzzer to monitor vibrations and provide real-time visual and audio alerts for potential seismic activity.
- Detects vibrations using the MPU6050 accelerometer
- Displays status on an OLED screen
- LED warning indicators:
- 🟢 Green → Normal conditions
- 🟡 Yellow → Moderate vibration
- 🔴 Red → Earthquake detected
- Buzzer alarm for strong vibrations
- Real-time vibration monitoring
- ESP32
- MPU6050 accelerometer/gyroscope
- SSD1306 OLED display
- LEDs (green, yellow, red)
- buzzer
- breadboard and jumper wires

This project uses the following libraries:
- Adafruit GFX
- Adafruit SSD1306
- Adafruit MPU6050
- MPU6050_light
Install them using the Arduino Library Manager.
- The MPU6050 sensor reads acceleration values on the X, Y, and Z axes.
- The ESP32 calculates the total vibration level.
- Based on the vibration threshold:
- Green LED indicates normal conditions
- Yellow LED indicates moderate vibrations
- Red LED and buzzer indicate possible earthquake activity
- The vibration level and system status are displayed on the OLED screen.
