1. A motion sensing device comprising:
- a printed circuit board (PCB) comprising a first plurality of parallel conductors and a second plurality of parallel conductors, said first plurality of parallel conductors being positioned on a first face of said printed circuit board, said second plurality of parallel conductors being positioned on an opposite face of said printed circuit board relative to said first face;
a power source coupled to said PCB; and
a first pin board comprising a first pin, said first pin board being configured for movement relative to said first face, said first pin being configured for electrical connectivity with at least one conductor of said first plurality of parallel conductors when said movement of said first pin is to a first juxtaposed position relative to said at least one conductor of said first plurality of parallel conductors and electrical discontinuity with one or more other conductors of said first plurality of parallel conductors.

Abstract
The invention pertains to a device and system which uses printed circuit board metrology to accurately measure relative motion between surfaces in one or more dimensions. The invention comprises a system on a chip (SOC) to periodically measure, log, and transmit relative motion data in an automated fashion either wired or wirelessly, allowing long term measurement of moving surfaces such as foundation movement, bridge movement, concrete movement, structural system movement, excavation movement, slope monitoring or tree growth monitoring.
