With the proposed drying system, farmers would be able to dry their farm produce using appropriate temperature and humidity control system. Abstract— this paper presents the design and implementation of a microcontroller based Seed Dryer Machine for farm produce interfaced with PC. Drying of farm produce and seeds in large quantity such as; melon, beans, corn, cocoa seeds, pumpkin seeds, rice, pepper seeds, tomato seeds etc., has been very challenging due to lack of drying facilities, drying space and poor weather. This gives low lifespan to the seeds and reduced quantity of stored seeds, which in turn could discourage farmers from further cultivations. In view of this problem, a microcontroller based Seed Dryer Machine is designed to aid and encourage farmers to dry in large scale different farm...
