This work presents the development of a didactic and interactive project, composed of four distinct modules: the first module is used for reading and controlling temperature; the second module, for reading and controlling luminosity; the third module is an RS232/CAN serial interface; The fourth module has a transceiver for serial communication between a personal computer and the network. The first, second, and third modules were built using PIC18F4580 microcontrollers with integrated CAN and were programmed in C language using the MikroC integrated development environment. The software for serial communication between the microcomputer and module III was written in Object Pascal language using the Delphi programming environment. Serial communication tests were performed between the microcomputer and the third module, obtaining positive results in data acquisition and transfer and command exchange through the CAN network, demonstrating a distributed data system among the modules on the bus.
