Watch winder based on the internet of things

Watches are wearable devices that support human activities as timepieces. There two types of watches based on their source driving energy: the quartz type, which uses a battery, and automatic mechanical mechanism to convert kinetic energy obtained when clock is used drive hands. Automatic type have time limit 48 hours or days until turns off stop. Therefore, watch winder needed make movements keep running while not in use. So, users can use again without need adjust time, date other functions. The produced this study employs stepper motor controlled by an ESP32 microcontroller via ULN2003 driver integrated circuit (IC). This because it has high rotor rotation precision prevent from over-winding problems. device also condition monitoring feature through application-based temperature humidity parameters. Users monitor control dial winder’s modules application.
