Sepatu berfungsi melindungi kaki dari kotoran, benda tajam, dan cuaca ekstrem. Namun, pada
musim hujan, proses pengeringan menjadi sulit karena ketergantungan pada sinar matahari. Sepatu
yang lembap dapat menimbulkan bau tidak sedap dan pertumbuhan mikroorganisme. Penelitian ini
merancang alat pengering sepatu berbasis elemen pemanas kawat nikelin dan sensor DHT22 untuk
memantau suhu dan kelembapan. Sistem dikendalikan oleh mikrokontroler ESP32 C3 Super Mini
dan menerapkan kontrol PID metode Ziegler-Nichols. Hasil pengujian menunjukkan sistem mampu
mencapai suhu setpoint secara cepat dan stabil tanpa overshoot signifikan. Bahan sepatu knit
menunjukkan respon suhu tercepat, stabil dalam 13 menit. Sistem pemanas mencapai suhu target
dalam 14 menit, dibantu kipas untuk distribusi panas merata. Waktu pengeringan tercatat sepatu
kanvas 40 menit, mesh 36 menit, dan knit 33 menit. Hasil ini menunjukan semakin cepat suhu
tercapai dan stabil, maka semakin singkat waktu pengeringan.

Design of a Shoe Dryer Device Using a DHT22 Sensor with Nichrome Wire

Heater

Shoes serve to protect the feet from dirt, sharp objects, and extreme weather conditions. However,
during the rainy season, the drying process becomes difficult due to reliance on sunlight. Damp
shoes can cause unpleasant odors and promote the growth of microorganisms. This study designed
a shoe dryer utilizing a nichrome wire heating element and a DHT22 sensor to monitor temperature
and humidity. The system is controlled by an ESP32 C3 Super Mini microcontroller and implements
a PID control system using the Ziegler-Nichols method. Test results show that the system is capable
of reaching the temperature setpoint quickly and stably without significant overshoot. Knit material
shoes exhibited the fastest temperature response, stabilizing within 13 minutes. The heating system
reached the target temperature in 14 minutes, assisted by a fan that ensures even heat distribution
within the drying chamber. The recorded drying times were 40 minutes for canvas shoes, 36 minutes
for mesh shoes, and 33 minutes for knit shoes. These results indicate that the faster and more stable
the temperature is achieved, the shorter the drying time required.
