A control circuit of automatic clothes?aired pole was designed by adopting NE555 timer. The state of weather changes is input into NE555 by opto?sensor or temperature sensor. The foreward rotation(up) or reversion rotation(down)of the motor is controlled by the action of monostable trigger inside the NE555. The input is controlled by illumination intensity of the phototriode,and so the breakover or cut?off of the triode is controlled for driving the external mechanical device and achieve the functions of clothes collection or clothes hanging . The circuit design of this automatic clothes?aired pole has the characteris?tics of low cost,quick reaction,low energy consumption,long lifetime and high reliability.
