BOSON: Capacitive Touch Sensor i8

BOSON Capacitive Touch Sensor uses capacitive sensing to detect direct touch on metal or indirect touch through plastic/glass. Sensitivity depends on metal surface size and covering material thickness; keep it at a certain desktop height (related to desktop material). With self-adhesive copper foil, it sticks easily to doors/glass. Pair with Arduino expansion boards for interactive projects. Note: Users need to connect and solder the copper foil sensor plate and sensor board themselves.
