Abstract: The photovoltaic (PV) array wireless sensor node and fault diagnosis system based on
STM32 is designed aiming at the problems of the existing methods of PV array fault detection are
lack of accurate and efficient and difficult to locate faulty PV modules. STM32F103 is used as the
core controller of the wireless sensor node hardware. It is mainly composed of power module, main
control module, data sampling module, data communication module. Using defined communication
protocol, the measurement results are reliably transmit
