Description

My mini project is to produce a device which can detect the earthquake, and produce some noise to alarm people that the earthquake is coming. Also, it provide people to send a message to the device to tell people what should they do durning and after the earthquake. I use the LSM9DS1 to detect the vibration. If the acceleration larger than some value, the mbed will play the .wav file in the sd card and use the TPA2005D1 Class D Audio Amp and the speaker to make the sound. In the meanwhile, the user can hear the noise and know the earthquake is coming and send a message by website to mbed to tell people how to deal with this situation.
