It cuts correctly in any direction you wish. https://www.youtube.com/watch?v=-qh2lVOS9UM
@SirGeekALot HEADS UP, then reread https://plus.google.com/106571792207579339017/posts/DR8hB1r1yD9 . The SN-04N2’s I received have an internal pull-up to the supply voltage, so in my quick bench test, with 24V supply, the output is normally low (0.01v but swings to supply voltage (24V) when you come in proximity of a piece of metal. Peter’s diode circuit will fix this issue and is necessary.
These are really 'electrostatic or capacitve sensors I believe, they switch when in close proximity to a piece of floating AL . Seem to work OK, just protect your tinyG inputs.
@cmcgrath5035 I bought some some 1N4148 diodes and some 10K resistors so I can use that exact circuit design, so hopefully I should be OK. Or are you implying I need to do something else to protect the TinyG inputs?
@SirGeekALot Nope, with that circuit you are good.
