液体検知センサ
Document Type and Number:
Japanese Patent JP7427471
Kind Code:
B2
Abstract:
To provide a liquid detection sensor capable of properly detecting water level without requiring an external power source.SOLUTION: A liquid detection sensor (1) has an air pole (2), a metal pole (3) opposing to the air pole at an interval, and a detecting portion (4) that detects electric characteristics according to changes in a contact area of the air pole and the metal pole with the liquid. According to the liquid detection sensor, by detecting electric characteristics changed according to an area of a cell reaction, it is possible to properly detect a liquid level by a simple structure without requiring an external power source.SELECTED DRAWING: Figure 1
