1. A module assembly comprising:
a plurality of modules capable of transmitting or receiving data by forming an open drain based one-wire communication bus upon mutual combination,
at least one module requiring the data transmission or reception among the plurality of modules,
performs first declaration for a transmission intention by outputting a low signal within a predetermined first arbitration time when at least one module is in an on state by sensing a state of the one-wire communication bus,
at least one module performing the first declaration for the transmission intention performs second declaration for the transmission intention by outputting a high signal within a second arbitration time, and
a module which outputs the high signal last within the second arbitration time secures final bus occupation.
