Abstract: Emergency monitoring for sudden environmental pollution accident requires that the monitoring data can be collected and transmitted timely and effectively in order that management can respond promptly to all kinds of unexpected dilemmas. Aiming at dealing with the drawback of the traditional wired transmission networks inconvenient pave, weak mobility, unsafe and unstable data transmission, a wireless sensor network node applied to pollution emergency monitoring system was designed. The system structured nodes with C8051F340 microcontroller and XBeePRO wireless transmission module on the part of the hardware and built the wireless sensor networks based on ZigBee. The pollution sources onsite data collection, transmission and processing were realized. The results indicate that the nodes are stability enough to cope with various emergency situations.
