Method for controlling portable device by using humidity sensor and portable device thereof

摘要

A method of controlling a portable device having a humidity sensor is provided. The method includes measuring a humidity level around the portable device using the humidity sensor when a call event occurs, comparing the measured humidity level with a preset threshold value, and controlling on/off of a display unit of the portable device according to a comparison outcome in order to prevent unnecessary energy or power consumption. The humidity sensor is located close to the microphone to detect when the user is talking to a communication partner and at the same time the display is in close proximity to the user's head and therefore invisible for the user.
