Wireless environment monitoring network and system

The invention relates to a wireless environment monitoring network which comprises a plurality of sub-nodes and head nodes, wherein two sub-nodes as well as the sub-nodes and the head nodes can communicate with each other; each of the head nodes comprises a plurality of environment sensors, a 433/355MHZ module, a GPRS module, a master control module and a power supply module; each of the sub-nodes comprises a plurality of environment sensors, the 433/355MHZ module, the master control module and the power supply module; the sub-nodes are used for monitoring environmental data; the environmental data monitored by each sub-node are amplified and are transferred to the next sub-node through the 433/355MHZ module, are successively transferred and lastly reach one head node; and the head node uploads the environmental data to a server through the GPRS module. The wireless environment monitoring network provided by the invention utilizes the Ad-Hoc Networks between sub-nodes as well as sub-nodes and head nodes and u
