The network nodes design of gas wireless sensor monitor

This article describes the toxic, flammable software and hardware design methods of gases wireless monitoring network nodes based on sensor array.By collecting signals with gases sensors and receiving and emitting data with wireless sensors network, we can measure the gas concentrations. We describe the toxic and flammable gas concentration measuring circuit and illustrate the theory. We choose the Atmega128 processor to fulfill the hardware design of wireless sensor network nodes, at the same time we select C language to accomplish ZigBee protocol.This system is suitable for detecting of the toxic or flammable gas, and it is easy to integrate with following equipment and controlled. It is benefical to protect our life and property.
