Automatic Cloth Drying Line Solution Using IoT

The weather in Bangalore, India is really unpredictable. It might rain during the hottest of the days or it might be sunny during the monsoons. This poses quite a challenge for drying the clothes outside. Solutions to this problem have been put across but they aren't cost effective and cannot be afforded by the common man. This paper talks about the design and implementation of a prototype called SMARTDRY that has a mobile roof, which is highly cost effective and serves the purpose. The system is developed using ArduinoUNO as the micro-controller along with a rain sensor as its main functional units. With the help of the rain sensor, whenever it starts to rain, a signal is sent to the Arduino UNO microcontroller that triggers the motor driver to enable the 12V DC motor, which moves the mobile roof hence covering the clothes and protecting it from rain. When the rain stops.the rain sensor alerts the micro-controller through a signal, which in turn triggers the motor driver, as a result of which the motor is enabled and the mobile roof is moved again in the opposite direction, so that the clothes are exposed to the open sky for drying. To communicate the status of the clothes with the user, the system has an ESP8266 wi-fi module which allows for real-time status sync of the system with the app that the user can use from any part of the world as long as he is connected to the internet.
