Abstract


Simple remote control (infrared remote control) has become the past, and products in the present era send instructions to products through connecting to the Internet. People expect that automation can make tasks easy, comfortable, fast and efficient. This paper introduces an innovative solution for humidity control and monitoring with the use of an intelligent drying box system. The proposed system utilizes a Peltier dehumidifier, a Blynk-based microcontroller (ESP8266), and a humidity sensor (DHT22) to maintain a certain humidity environment for storing moisture-sensitive materials such as electronic components, camera lenses, and musical instruments. The Blink application monitors the humidity level remotely through smart phones or computers, allowing users to receive notifications of humidity level fluctuations and make necessary adjustments to the humidity value in the box.

The smart drying box system offers several advantages over traditional humidity control methods. Firstly, the system provides an affordable and practical solution to maintain a certain humidity environment, making it suitable for personal or commercial use. Compared to traditional drying boxes that can stabilize humidity values on the market, the proposed system is more cost-effective, making it accessible to a wider range of users. Secondly, the Blynk app enables remote control and monitoring capabilities, allowing users to make necessary adjustments from a distance. This feature makes the system ideal for applications in which constant monitoring is required, such as museums, archives, and galleries.

Moreover, the experimental results indicate that the intelligent drying box system is effective in maintaining a specific humidity environment with a certain variation of relative humidity. This finding confirms the system's efficiency in regulating humidity levels and ensuring the protection of stored materials. The system's simple design and user-friendly interface make it easy to operate, requiring no specialized knowledge or training. Overall, the proposed system provides a promising option for humidity control and monitoring in various applications in fields such as photography, electronics, and music.
