Monitoring Temperatures in a Solar Dehydrator

This project presents the implementation of an in real time automatic temperature monitoring system in a solar dehydrator, this for educational purposes and collaborative research in the area of Industrial Maintenance. The infrastructure for monitoring and storing data is developed through an Arduino network. This article presents the main considerations of the development of this project, such as temperature storage, verification procedures, the automatic system programming procedure in the Arduino microcontroller, and the installation of the monitoring prototype, consisting of type J temperature sensors and an Arduino microcontroller. The process consists in the monitoring of temperature in the dehydration of apples. The final application shows that an adequate temperature monitoring is a crucial factor in order to achieve well dehydrated product. As well, the evaluation of the temperatures can assure a suitable thermodynamic control to optimize resources with a significant contribution to the innovation and development of automatic systems.
