Design of the automatic shoe dryer

Abstract

Shoes are parts of basic human needs. Many of them are typically selected based on different needs of the users. There is always a problem related to shoe care. In many cases, people prefer laundry services to take care of their shoes, but it commonly takes a long duration, about one to two days. Another thing is that the drying process is done through direct sunlight exposure, and that can damage the materials and fade the colors. Therefore, this system is designed and implemented to facilitate the process of drying shoes and protect some shoes that cannot be dried using sunlight. The hardware design is featured with control and software, which are then implemented for further analysis to obtain the desired results. The whole system control is derived from the ladder program within the Programmable Logic Control (PLC). To identify shoes that have been dried or ones that cannot be detected by the SHT11 temperature and humidity sensor, which is connected to the ATmega16 microcontroller as a serial data communication. The implementation resulted in a novelty, namely digital automatic shoe drying system without the use of sunlight.
