Abstract: The wireless sensor network node of roof abscission layer was experimental studied based on ZigBee and the energy consumption of the node was analyzed. The result is that the wireless sensor network node can be used independently, can also be used as a wireless sensor network node. When the node used exclusively, the node can monitor the condition of the roof abscission layer based on the light shutter devices. When the node used as wireless network node, the network architecture is the overlay tree architecture, which has the self-organizing and self-recoverability properties. The whole tree architecture is communicated between the node and the neighbour nodes. The local mesh architecture is communicated between the node and the next nearest neighbour node.
