Modeling and Application of Rain-Light Sensor in Automatic Clothes Drying Design

The development of science and technology has experienced such rapid growth, thus encouraging humans to try to overcome all problems that arise around them and ease the work around the environment through automatic control systems.One of the technologies currently being developed is the Arduino microcontroller.Based on the problems often experienced by students when leaving clothes to dry in the dormitory.If it rains or bad weather, it can be a problem if you do not have time to lift the clothesline so that dry clothes become wet with rainwater when there are no dorm residents because they are on campus.Given these problems, the author designed an automatic drying room prototype using a rain sensor and light sensor based on an Arduino microcontroller.The components used are a drying room and roof, a light sensor and water sensor as input, an Arduino microcontroller, breadboard and jumper cables, a power bank as a processor, and a servo motor and LED lights as output.A servo motor automatically moves the roof of the clothes' drying room, and the LED lights turn on, according to input from the light sensor and rain sensor, according to the conditions received by the sensor.
