Remote Supervision of Ambient Temperature Using Wi-Fi ESP8266 Controller Via MIT Android Application

Over the past decade, significant advancements in electronics, computer science, and communications have propelled the evolution of embedded systems within the Internet of Things (IoT) domain. This paper focuses on the implementation of a remote temperature monitoring system, leveraging a Wi-Fi card integrated into a smartphone Android application. The development process involves utilizing the MIT App Inventor IDE, a user-friendly visual programming interface, along with the ESP8266 microcontroller for platform development. The temperature sensing capability is achieved through the integration of the LM35 sensor. The system enables real-time temperature monitoring and data acquisition, facilitating informed decision-making and timely responses to temperature variations. Through rigorous testing and evaluation, the effectiveness, accuracy, and reliability of the system are demonstrated. The combination of cost-effectiveness, ease of use, and widespread availability makes this solution suitable for a range of applications in various environments.
