The second stage that makes this electronic labeling system is the main device which is composed by a computer in which is stored the database store products, an Arduino mega module where the information sent from the PC is processed and through the serial port transmits that information in the form of characters to a xbee module that serves as coordinator, to send such data to the router xbee (labels).
