A Fire Monitoring System in ZigBee Wireless Network

In the work, a kind of low power, multi-parameter composite fire detection node is designed, which can detect temperature, smoke concentration and CO gas concentration. And combining with the WSN (wireless sensor network), a real-time wireless fire monitoring system is established. This system is applied in fire detection of special circumstance represented by the ancient buildings. The hardware and software implementation is based on 2.4GHz wireless communication chip CC2430. ZigBee protocol is adopted in the system to form reliable wireless communication. The result of experiment shows that the sensor nodes can connect each other and form net automatically and the system works effectively and stably in wireless fire detection.
