Example 2: Graphing the Human Presence Sensor Serial Data
The next example takes the derivative of a single channel and displays this on the serial plotter. The code for this example is shown below. Notice how
you can change the sensitivity of the Human Presence Sensor using the sensitivity value. It is set at 50 by default, and values lower than this will
yield higher sensitivity.
