DUST SENSOR DEVICE AND THE METHOD USING THE DUST SENSOR

摘要

PURPOSE: A dust sensor apparatus and a dust sensing method using the same are provided to apply to various places in which the air velocity is extremely changes and to rapidly offer an agreeable environment by transferring the measured value through a communication module on a real time basis. CONSTITUTION: A dust sensor apparatus comprises a sensor case(10), an inner fan(12), and an interrupting blade. The sensor case comprises a sensor and a communication module. The inner pan rotates inside the sensor case at a constant speed to control the air flowing into the sensor case. The interrupting blade sets a direction to reduce the air velocity flowing from the same direction where the interrupting blade is tilted to. The interrupting blade is formed into a oblique shape to prevent that the air flows into the sensor case.
