Sensor for humidity and management system therefor

Abstract

The present invention relates to a sensor for humidity, etc. which has high precision, very small electrical power consumption and simplified composition, and a management system therefor. The sensor and the management system therefor according to the present invention are also economical. The sensor according to the present invention comprises two electrode pads and an absorption layer for absorbing moisture, etc. between them, and detects a capacitance variation and a resistance variation between the electrode pads, measuring humidity, etc. in real time. In the sensor, one or both of the electrode pads can be made by printing or coating a conductive material on a paper pad or a fabric pad in a mesh shape of fine lines. Or the electrode pads can be fabrics with fine thread of a mesh-type electric conductor coated by an absorptive material having an insulating property.
