Desenvolvimento e implementação de um sistema automatizado de varal inteligente utilizando arduino para aplicações em automação residencial

Home automation enables the development of technological solutions designed to facilitate everyday activities through the integration of sensors, control systems, and actuators. In this context, this study aims to develop and implement an automated smart clothesline system using an Arduino Uno, capable of retracting and extending its structure according to environmental conditions detected by sensors. The research is applied in nature, based on a bibliographic review and associated with the development and experimental testing of a prototype, using a predominantly qualitative approach. The system consists of an Arduino Uno, a Sensor Shield V5.0, a rain sensor, an LDR light sensor module, an active buzzer, and a servo motor. The programmed logic retracts the clothesline when rain or low light levels are detected and extends it when the conditions defined in the code are met. The reported results indicate that the prototype responded to simulated environmental changes, demonstrating functional integration between sensors, electronic processing, and mechanical actuation. However, limitations were identified regarding the servo motor's mechanical capacity, the need for sensor calibration, and the absence of quantitative performance indicators. It is concluded that the project demonstrated the initial functional feasibility of automating a clothesline on an experimental scale, providing a basis for mechanical, electronic, and control improvements required to assess its suitability for residential applications.
