The development of science and technology today, Internet of things is a newnetwork form, people paid much attention to it. It is in the computer based on theInternet, the use of radio frequency identification technology, the wireless datacommunication technology, structure a achieve global items information sharereal-time physical Internet. Through the wireless data communication technology canachieve objects and object, the object and the communication between people anddialogue. And the wireless data communication technology, the main technology forwireless sensor networks, wireless sensor network integration the sensor, embeddedcomputing and wireless communication technology, can collaboratively perception,acquisition and processing coverage of the area of information, and through multiplehops self-organizing network transmission to the observer, thus will objectivephysical world and logical link information world, greatly expands the existingnetwork function and the ability of people to recognize the things. Wireless sensornetwork life cycle is very important, and its survival period is by the externalenvironment, node transmission energy loss, node initial energy factors that decision.Try to prolong the survival of the wireless sensor network research work cycle isnecessary.This paper mainly expounds the content networking research background andsignificance, and illustrates the wireless sensor network system structure anddevelopment and application, this paper focuses on its routing protocol, especially forLEACH agreement makes a detailed instruction, according to the shortcomings ofLEACH agreement to the lower power consumption improvement, and in OMNET++under the environment of the LEACH agreement and improvement of the agreementLEACH simulation, by comparing the result of improved LEACH agreement thatprolong the network life cycle.Then, this paper designed based on wireless sensor network technologyagricultural canopy of the temperature and humidity data acquisition and monitoringsystem. This system USES a TI company’s CC2530wireless transmission chip andtime Ryan company DB130-and the combination of temperature and humiditysensor solutions, can complete on agricultural production of vegetables, fruit trellis environment temperature and humidity of the information in the real-time dataacquisition and monitoring. Among them, the temperature measurement accuracy of+/-0.5℃, moderate measure accuracy of plus or minus4.5%RH. Test results showthat the system reliable operation and to reach the design requirement.
