Title:
無線タグを利用した水位検知装置
Document Type and Number:
Japanese Patent JP4144004
Kind Code:
B2
Abstract:
To provide a water level detection device which has few components and is simple in a circuit constitution.
A radio tag 6 comprises an antenna 3, a radio tag IC4 and a switch 5. The switch 5 is controlled with an ON/OFF control, using a water-level sensor. Accordingly, if the water-level sensor detects a predetermined water level and emits its signal, the switch 5 becomes ON. The radio tag IC4 automatically emits a predetermined data by radio wave via the antenna 3. That is automatic feeding of hot water in a bathtub 1 or the like, overflow detection of a washbasin and stoppage of water discharge, and the overflow detection and a feed water stop means or the like, of a low tank of a flush toilet.
