Design of Node in Family's Fire Prevention Based on WSN

At present, wireless sensor network is widely used in sensor technology. While to design the node of WSN which is powerful, good fault tolerance, low power consumption and cheap is essential in wireless sensor network. In this article, A Family's fire prevention method using WSN was described. Which was selectively analysed is the hardware design in sensor node and sink node. At last, we discussed the software flow of this two kinds of nodes.
