## Exercise 1 - Test of the Sound Sensor ### Exercise 1 - Test of the Sound Sensor
### Goal #### Goal
The goal is to give descriptions of the reading from the sound sensor from different distances. The goal is to give descriptions of the reading from the sound sensor from different distances.
### Plan #### Plan
We will test the sensor with different loudness levels at different distances. The tone used is a 440 sinus. We will test the sensor with different loudness levels at different distances. The tone used is a 440 sinus.

### Conclusion #### Conclusion
As seen in the table, the distance of 25 cm with both 50% and 100% volume results in the same sensor reading with the value of 2. This is odd, and we are not quite sure why this.

In regards to the other readings the results shows a good connection with the loudness level, however, if you didn’t know the two loudness levels, it would be hard to derive their relation them from the data readings.
