Post-harvest loss of a large scale of the horticultural products is also experienced because of continued use of primitive and ineffective methods of storage in rural and underprivileged areas. Lack of real-time modulation of key parameters, including temperature, humidity, and airflow, leads to un-balanced dehydration, microbial growth, and loss of nutritional integrity. Thus, a large portion of food is not consumed because of the lack of post-harvest practices rather than production shortcomings-further increasing the state of food insecurity, eroding the level of economic profitability for farmers, and aggravating environmental decay by wasting critical resources. To minimize post-harvest spoilage, the paper offers a more complex intelligent dehydration system featuring RS-232-equipped sensors that can allow real-time temperature, humidity, and airflow measurements. The system uses dynamic control algorithms and is powered by a microcontroller-based fuzzy logic controller and aided with an IoT dashboard, thus becoming an autonomous system that controls the thermal and airflow dynamics. Measured data is sampled at one-second frequencies that guarantee the best psychrometric conditions for different crops. Designed using modular and cost-efficient parts and optimized by energy demand-sensitive scheduling, the design enables sustainable conservation and restrained expenditure on power consumption and secures the quality of the products. Preliminary results suggest that the system can be used to homogenously de-hydrate produce, dramatically reducing the time required to dry products and maintaining higher nutritional properties compared with traditional drying techniques. This smart sensor system offers a way to reduce waste after harvest that is easy to expand, affordable, and good for the environment.
