	| Abstract | 
	Smart factory control, required in small-scale factory, is an accurate and clear function that controls factory devices by transmitting sensor data to a server and monitoring it on smart devices. Accordingly, in this paper, a microcontroller capable of information transmission and device control was selected, and a sensor interface, communication using a Wi-Fi shield, and data communication format with the server were designed. And it was proven that the proposed interface method is useful by actually implementing the relevant part, connecting it with a microcontroller(Arduino), server, and smart device, and checking its function.  |
