Abstract:

This article presents a soil temperature sampling system based on the GPRS and an environment survey plan based on the wireless sensor network.The wireless sensor network consists of a large number of wireless sensor nodes which are randomly distributed.All theses nodes are connected with each other by wireless communication technology,capable of data sampling,processing,wireless communication and auto network connection.Telosb platform is used to complete the design of the hardware structure of the sensor nodes and the software design is completed on the TinyOS.The whole system can solve the humidity and temperature sampling problems for the target zone,realizing both the single and muti-hop data transfer meanwhile the long term dynamic surveillance can be also realized by efficient and reliable GPRS long range transmission.

Key words: GPRS;real time collection;Telosb;TinyOS
