Abstract
The present invention provides a humidity sensor including a first conductor, a second conductor, a power supply unit, and a current sensing unit. The first and the second conductors are separated from each other for a predetermined distance and are placed at a predetermined place. The power supply unit supplies high voltage to the first conductor, and the current sensing unit senses a change of current in the conductor and generate a signal in association with the change of the current. Therefore, the humidity sensor may operate in any environment, such as high temperature and high pressure.
