PROBLEM TO BE SOLVED: To provide a device and a method which monitor the state of (under-floor, rear wall, rear ceiling) inside (floor surface, wall surface, top surface) which form indoor spaces in a house or the like. SOLUTION: A plurality of signal lines L-V, L-H are horizontally and laterally laid so that meshes are formed in parallel to the floor, a plurality of sensors V, H are fixed at equal intervals on the signal lines L-V, L-H, and each sensor V, H sends a measurement result to a server device 1 via terminals T-V, T-L together with identification information. Thus, if water leakage is occurred at a place indicated by a reference code P in a buried water piping having main pipes 3 and branch pipes 4, sensors H35, V42, V52 in proximity, which indicate dense hatching, firstly detect the signal and then adjacent sensors H25, H34, V43, V53, which are a little bit thinner hatching, detect the signal. Therefore, even if the water piping has a complicated shape such as having branch pipes 4, an inconvenient part P is easily, correctly identified for efficient repairing.
