Our UbiSound Home Monitor meets the expected functions including precisely detecting the door close and knock door. Also users can receive the alarm SMS message in real time.
For the future work, we expected that additional classification categories could be explored. There are many other useful activities that have very unique frequency response, and we could expand the functions of our device further. For example, door bell, fire alarm, etc. It would also be beneficial to add additional sensors to the board, including but not limited to camera and speaker. Therefore, it adds possibilities for user to interact with the device. For example, we can allow the user to talk to the people outside of the door through the phone, or turn on the camera when needed.
