HUMIDITY SENSOR CAPABLE OF SELF-REGULATING TEMPERATURE COMPENSATION AND MANUFACTURING METHOD THEREOF

摘要

A humidity sensor capable of self-regulating temperature compensation and a manufacturing method thereof overcomes the inaccuracy caused by the resistor value of a conventional humidity-sensitive element changing depending due to changes in the temperature. The present invention proposes disposing two different humidity-sensitive elements in a humidity-sensitive substrate, wherein one humidity-sensitive element includes a saturated salt solution. The humidity-sensitive substrate has two different humidity-sensitive elements for achieving a self-regulating temperature compensation feature. The present invention of the humidity-sensitive element having the saturated salt solution can maintain the amount of humidity in the air regardless of the temperature.
