PURPOSE: A sensor assembly for a washing machine is provided to measure a minute water level in a water container of the washing machine by using a piezoelectric sensor. CONSTITUTION: A piezoelectric sensor(300) outputs variation rates of power according to pressure variation by using a piezoelectric effect. A space(400) supports the piezoelectric sensor. An inlet guides air in order to draw the air into the inside of a cover(200). An O-ring(410) shields a gap between the cover and the piezoelectric sensor. A sealing member(420) blocks the inflow of a foreign substance through a gap between a case(100) and the cover. |
