"220V Cooling Fan" mainly by the MCU, proximity detection, dumping detection, temperature detection major components, man-machine interface:
 MCU using Motorola's 8-bit microcontroller MC68HC908AP64.
 "220V Cooling Fan" proximity detection module uses an electric field sensor Motorola MC33794, the use of electric fields on the human body imaging technology to detect approaching.
 Dumping detection module using Motorola acceleration sensor MMA1260D, body dumped on the alarm, forcing the motor to stop working.
 "220V Cooling Fan" temperature detection module DS18B20, it is mainly used to monitor motor temperature chamber docile.
 Man-machine interface includes an infrared remote control, a keyboard module and LCD display module, fan interaction with the user information.
