|
|
* Uses a high value resistor e.g. 10M between send pin and receive pin
|
||
|
|
* Resistor effects sensitivity, experiment with values, 50K - 50M. Larger resistor values yield larger sensor values.
|
||
|
|
* Receive pin is the sensor pin - try different amounts of foil/metal on this pin
|
||
|
|
* Best results are obtained if sensor foil and wire is covered with an insulator such as paper or plastic sheet
