Warmer in the field of daily life has a very wide range of applications, traditional heater due to the lack of temperature control, automatic power-off, graded heating and timing function, not only slow warming, large power consumption, but also very insecure, has been unable to meet the user's demand. Aiming at the deficiency of the traditional heating function, this paper elaborate design and produced a set of intelligent heating system based on 51 single chip microcomputer, the system has a graded heating, constant temperature control, digital display and automati...
