Design of Intelligent Indoor Perfume Instrument Based on C8051F300

An intelligent indoor perfume instrument based on C8051F300 is presented in this paper,and the working principle of perfume instrument particularly introduced,making sure that circuit broken down when the current of perfume instrument head is more than 1.05A or the heating time is more than 8 minutes,avoiding effectively perfume is too much.This perfume instrument is good use of the feature of C8051F300(MCU),the relay is disconnectted and the LED broken down when sampled current and heating time is more than critical value through programming.The perfume instrument could be widely used in air purification of the sitting room,bedroom,studying house,kitchen,in-car confined space,etc.
