According to the national standard GB28184-2011 “fire-fighting equipment power monitoring system”, this paper study and design a voltage-current monitoring sensor to solve that many products are lower accuracy, unstable communication and not meet the national standard specifications. The design innovations include that the sensor sample current and voltage by the RN8209G chip and communicate by the CAN bus. The current sample accuracy can range up to 1%.The design have passed the national standard GB28184 in 4.7 Table 1 of the experimental requirements. The test includes about the high temperature test, surge immunity and electrical fast transient pulse immunity.
