PROBLEM TO BE SOLVED: To provide a wiring method and a wire-saving method of circuit wiring of a mapping sensor which detects presence and keeping position of a thing in a storage case or on a storage shelf and hands state information to a management system, when keeping a thing like a thin board. SOLUTION: The mapping sensor circuit is a circuit and a mapping sensor circuit which constitutes a circuit performing state holding of each mapping sensor module and a circuit for fetching the data read-out to a buffer memory once, while reading-out state of each sensor module, provided separately and transferring the data to a management system or a control unit, and simply connects with four connector cable wiring between each module that is not related to the number of mapping sensor modules, and as a result which can be performed for wire-saving, without increasing the wiring number even when sensor interval or the amount of sensors are different.
