可自动收回的旋转式智能晾衣架设计

n intelligent airer with the function of automatically retracting is Designed. The signals collected by temperature sensor, light sensor, tension sensors and position sensors are input signals.The action of the airer is achieved by two motors controlled by the microcontroller. The design of the airer has the features of retracting automatically with high temperature or weak light, and extending automatically when the temperature and the light is normal.When it is raining or the clothes is dry ，the airer automatically retracts and the beeper chimes. The rotary circular airer saves space and avoids damage to clothes due to prolonged exposure in the sunshine.
