Abstract

This study discusses the design and implementation of a real-time room temperature and humidity monitoring system based on an Arduino microcontroller and a digital DHT11 sensor. Ambient temperature and relative humidity are crucial factors affecting human health, comfort, and the operational stability of indoor electronic equipment. Traditional manual measurement methods are deemed inefficient because they fail to provide continuous, responsive data regarding environmental fluctuations. To overcome these challenges, this system was developed by utilizing the DHT11 sensor as a physical input device, while the Arduino board processes the collected data and displays it live on an LCD screen. The research methodology adopts an engineering approach, incorporating hardware integration, software programming, and prototype testing. Experimental evaluations were conducted across different daily time slots and applied to a case study monitoring a tempeh fermentation process over a 48-hour period. The test results demonstrate that the proposed system effectively provides stable, accurate, and real-time readings within the operational tolerance of the sensor. In conclusion, the system successfully replaces manual readings and offers a practical, low-cost solution for indoor environmental tracking with promising potential for future Internet of Things (IoT) expansion.
