Abstract

In proportion to the growth of science and technology, human comfort and requirements are growing. Drying clothes is a time-consuming task if you must wait and maintain their dryness. This is because people are occupied with household chores or have busy working hours, leaving them with insufficient time to complete all domestic tasks, such as picking up clothing from their clothesline. In this project, hardware and software components are used to make it work. This project has three input sensors which are rain sensor, light, temperature and humidity sensor. Rain sensor works by detecting rain fall and notify the user when it rains. From here, the input from the rain sensor will determine whether the clothesline will extend or compress based on the conditions. Temperature and humidity sensor on the other hand works by monitoring the surrounding air of the clothesline and this will be displayed on the user interface of Blynk Application while light sensor will just indicate if it is bright or dark outside. NodeMCU ESP8266 will act as microcontroller where it will communicate with Blynk Application via Internet of Things (IoT) to send notification or data to the user’s mobile phone. To extend or compress the clothesline, a servo motor will be used either after the rain sensor detects the presence of water or manually by the user. The software part that is used in this project are Arduino IDE and Blynk Application. Arduino IDE works as a coding platform for the working of NodeMCU ESP8266 and for the system to run whereas Blynk Application will act as a medium for the notification or data to be displayed for the user. This project has a significant influence on busy people by relieving them of their anxieties about their garments outside, allowing them to focus on other vital matters.
