Abstract: Aiming at the current situation of traditional fire alarm system, a ZigBee wireless fire monitoring and alarm system based on CC2530 as the core control chip is designed. The system consists of a coordinator node, a terminal sensor network node and a host computer. The coordinator node establishes ZigBee network. The terminal sensor network node collects external environment information and uploads the data to the host computer through the coordinator node to achieve real-time monitoring of environment.This paper introduces the hardware design and software control of the whole system in detail. Through many tests, the system has the advantages of stable performance, low power consumption, good scalability, convenient maintenance and low cost, which can be widely used in various environmental fire monitoring.
