To provide a compact and user-friendly building diagnosing system which reduces power consumption, with high safety.
The building diagnosing system is constituted of relay modules 10 connected in tandem by a plurality of coaxial cables 40, and RFID modules 20-1, 20-2, ... having a plurality of sensors 26, and has the relay modules 10 between a transmission line buried on a wall and a reader/writer module 50 to separate the transmission line from the reader/writer module 10. The transmission line needs no power supply when not in use. When in use, electrical power is supplied to the transmission line from the reader/writer module 10 via the relay modules 10. A detection signal of a sensor 26 connected to the RFID modules 20 is read by the reader/writer module 10 via the transmission line and the relay modules 10.
