MONITORING DEVICE

摘要

A monitoring device according to an embodiment of the present invention includes a master device which generates first sensing data by detecting an output voltage or an output current of a first photovoltaic array; and at least one slave device which is connected to the master device by a serial expansion port, generates second sensing data by detecting an output current of a second photovoltaic array, and transmits the second sensing data to the master device. The master device transmits the first sensing data and the second sensing data to a wireless network.
