Magnetic sensor kit - Prop kit to detect the placement of 4 objects. Connects with simple jumpers with one button programming for the entire chain. Digital sensors can replace more sophisticated RFID detection systems. This system works great when the prop placements have some registration to the surface they sit on, ie a chess puzzle, etc.

When using the same magnet in two positions, the goal is to stay
within the sensitivity range but provide enough ‘margin on each side for
accurate detection and discretion (difference between the two). When combined with utilizing both poles, 4
or more combinations can be accurately detected.
