WATER LEVEL OF BATHTUB DETECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a water level of a bathtub detection device with high flexibility in installation while dispensing with the pressure detection part. SOLUTION: The device is provided with a plurality of wireless IC tags 13-15 and a reader or a writer 12. When the wireless IC tags 13-15 are immersed in the water, the radio waves are shielded, so the water level is specified by detecting the number of wireless IC tags immersed in the water. Thereby, the water level of the bathtub detection device with a high degree of freedom for installation can be provided. COPYRIGHT: (C)2006,JPO&NCIPI
