Design and Implementation of an Automated Drying Line System (ADLS)

Abstract—Traditional clothes drying lines are unable to protect clothes from rainfall, theft, strong winds, dust, stains, birds dropping and insects. This makes life unbearable. This paper seeks to design a system that will not only help dry clothes but also offer protection of clothes from rainfall, theft, strong winds, dust and stains. The designed system has a tube that directs sun rays from outside into a box-like container within the room which contains the hung clothes. The tube with its converging lens direct sun rays onto a reflecting plane which in turn direct the rays into the box uniformly with the help of a diverging lens. The interior surfaces of the box are coated black to retain heat. The system has a humidity sensor to measure the dryness of clothes and notify the user via an LED blink and the sound of a buzzer. The system has a fan that can be turned on to expedite the drying process of clothes within the system. It goes off automatically when clothes are dried thereby conserving energy. The system receives instructions from Arduino Uno. All codes were written with Arduino IDE. Keywords— Serial Arduino, Arduino Nano, Arduino Uno, Arduino 101, LED
