PURPOSE: A device for sensing physical quantity and dust collector using the same are provided to reduce malfunction generation rate by preventing the friction with dust by sensing temperature. CONSTITUTION: A device for sensing physical quantity comprises a weight detecting sensor(400), a guide unit(100) and a supporting wire. The weight detecting sensor is arranged on the outer one side of a reservoir(30). The guide unit is arranged in reservoir and includes the body bored to the dust passing direction. A dust inlet(101) area is bigger than a dust outlet(102) area. The supporting wire interlinks the weight detecting sensor and guide unit.
