| 摘要 |
<p>The present invention relates to a humidity sensor and a system thereof and, more particularly, to a humidity sensor and a system thereof which can have a simple structure by coating a conductive resistance body with a cheap and simple carbon material and can sense the separation of the sensor and humidity. The humidity sensor comprises: a pad with water permeability; two or more conductor electrodes which have a consistent resistance value coated on the pad; and an auxiliary electrode and a main electrode which is electrically connected with a pair of the electrodes, and is composed of the auxiliary electrode with a difference resistance value from the electrodes in order to sense the separation or defect of the humidity sensor and humidity.</p> |
