PURPOSE: An intake/discharge ventilation fan using a sensor is provided to operate the ventilation fan according to a synthetic pollution degree of a room by various gas and dust and supply oxygen by a lack amount, thereby maintaining a room pleasantly. CONSTITUTION: An intake/discharge ventilation fan using a sensor includes a sensor part(100) having an oxygen sensor part(110) for detecting oxygen among various gas and dust mixed in a room space, a carbon monoxide sensor part(120) for detecting carbon monoxide, a butane gas sensor part(130) for detecting butane gas, a methane gas sensor part(140) for detecting methane gas, and a dust sensor part(150) for detecting dust, a microcomputer(200) for generating a synthetic data for the oxygen to the dust sensed by the above sensor parts, and controlling a motor speed control part(400) according to the generated synthetic data or the operation of the oxygen sensor part, a display part(300) formed of various colors of light emitting elements for emitting light corresponding to the synthetic data generated by the microcomputer, and an exhaust fan(700) for rotating by a motor(500) to discharge the carbon monoxide gas, the butane gas and the dust mixed in the room space to the outside according to the synthetic data generated by the microcomputer.
