Design Tips for Moisture Tolerance
When designing a moisture tolerant application:1 Provide as much spacing as possible between buttons
2 Provide significant spacing between buttons and nearby ground planes
3 Route all electrode connection traces on the PCB layer furthest from the surface
4 Set sensor idle states to High-Z (floating) so that nearby sensors don’t provide coupling points that can cause false detections
5 If possible, use a non-conductive enclosure for the product
