Abstract : This paper presents the design, implementation, and performance analysis of an IoT-enabled solar dryer for agricultural produce. The system integrates temperature and humidity sensors, a microcontroller, and a buck converter for voltage regulation. Real-time data monitoring and control are achieved via a web dashboard. Experimental results show significant improvements in drying efficiency and energy savings compared to traditional sun drying. “Blynk”, a cloud- based IoT platform was used to develop remote monitoring system that enables constant monitoring of the temperature, humidity of products in the solar dryer. As a result, the effectiveness of upgrading traditional sun drying with IoT technology can help reduce the challenges and disadvantages that fish drying farmers have faced. The study, with correct drying monitoring criteria, could serve as a model for other food products that can be dried.
