I'm wondering if you can help me with a suggestion for some type of prepackaged sensor to detect metal proximity. Kind of like metal detector except I only need it for small area about 2" square and the distance to metal is ~5mm. But not like metal detectors where I'd like to have just the tips of wires near the detection point.
Here's a picture of that I need. TIA.
