| Summary: | 碩士 === 國立雲林科技大學 === 電機工程系 === 107 === This experiment is based on sensing earthquakes, using the Arduino Uno control board with the ATmega382 MCU controller and the Arduino software driver, and using the GY-291-ADXL345 for sensing the tilt angle. Buzzer and LED light as an alarm function, using one touch sensor module as a switch to control 5V LED light, many various Arduino hardware and software equipment.
And design a three-axis mechanism, through the analog method, when the sensor knows that there is an earthquake, it will receive the signal, and start to trigger the alarm after receiving the signal, at last, light source and the external power supply for this system, the external power supply will not cause the device to fail due to power failure.
Keywords：Arduino、Arduino Uno、ADXL345、Earthquake、Three-axis mechanism
