Since the mist of the automobile windshield interferes the driver's sight and safety, it is needed to develop an automatic de-mist equipment with coupling of the Automatic Temperature Control (ATC) unit of an automobile. To be able to coupling between units, we have used RS232C and made the interface board which can communicate between them despite of the difference of communication speed. The Mist possibility (MP) was as the difference of temperature between the dew point and the surface temperature of windshield glass. The automatic de-mist control system begins to operate before the mist covers the inner windshield glass. It was observed that the automatic de-mist control system operates well and removes quickly the mist as long as possible.
