In the current era, technology is deeply integrated into daily life even as many individuals still remain distanced from these advancements. This research aims to develop a temperature-controlled electric fan that adjusts its speed automatically according to environmental temperature changes. The objective is to design a system wherein the fan regulates its operational speed independent of user intervention, thus ensuring comfort by responding to room temperature. The implemented system utilizes an ATMega328P microcontroller that senses room temperature and adjusts the fan speed accordingly. The methodology involves the design and programming of the control system integrated with components including an LCD, transistors, and resistors. Results demonstrate that this automated system not only enhances comfort in various living areas but also provides significant assistance to individuals, such as those with disabilities, who may struggle to manually adjust fan settings. Overall, the project highlights the potential of automation in home environments to improve convenience and efficiency in temperature regulation.
