Ambient Sound Detection Using Arduino

Arduino microcontroller connected to a sound sensor will be utilized to test the noise levels of different areas

Hardware Used

- Arduino Uno A000066 microcontroller

- 2 LED

- Button

- SD card and Card Reader

- DFRobot DFR0034 analog sound sensor

- Wire

- D/C Power Source

Code Used included in file or view photos

As written in included code:

- Plug in device

- Insert SD card

- If red light is on continue (if not refer to hardware or software for troubleshooting)

- Push button (green light will flash)

- let device collect for 2 hours.

- Repeat for multiple data sets.

- Remove SD Card from device

- Insert in computer

- Data will be in .txt file a unit less value 0-1000

* Note data is not measured in dB. Transfer function required or Calibrate using constant noise to create metric for your needs.
