A system by using computer techniques， wireless communication and sensors is designed for monitoring electroplating current of PCB. This monitoring system uses wireless sensor nodes based on NEF9E5 MCU as the center unit, and uses a Hall current-sensor and its peripheral circuit. The system implements the wireless communication between wireless sensor nodes and the computer by using the method of time partitioned multiple addresses. The tested results show that the system is practicable, reliable and low-cost，and could be widely applied and developed in the future．
