<p>Disclosed herein is an apparatus for automatically controlling a ventilation fan. The apparatus includes a controller which is connected between an electric power cord of the ventilation fan and an electric power socket, measures status information including smell, smoke, humidity, dust, temperature, and gas leakage of a predetermined indoor space, compares measured data with predetermined reference data, and drives the ventilation fan if the measured data is greater than the reference data; and the ventilation fan which is driven under the control of the controller. The apparatus includes at least one wireless sensor which is directly connected to an electric power socket, measures status information including smell, smoke, humidity, dust, temperature, and gas leakage of a predetermined indoor space, converts measured data into a radio frequency (RF) signal, and transmits the RF signal; a controller which is connected between an electric power cord of the ventilation fan and an electric power socket, compares the measured data received from the wireless sensor with predetermined reference data, and drives the ventilation fan if the measured data is greater than the reference data; and the ventilation fan which is driven under the control of the controller.</p> |
