Due to unevennatural distribution of rain water it is very difficult for farmers to monitor and control the distribution of water to agriculture field inthe whole farm or as per the requirement of the crop. There is no ideal irrigation method for all weather conditions, soil structure andvariety of crops cultures. Farmers suffer large financial losses because of wrong prediciton of weather and incorrect irrigationmethods. In this context, with the evolution of miniaturized sensor devices coupled with wireless technologies, it is possible remotelymonitor parameters such as moisure, temperature and humidity. In this paper it is proposed to design, develop and implement awireless sensor network connected to a central node using ZigBee, which in turn is connected to a Central Monitoring Station (CMS)through General Packet Radio Service (GPRS) or Global System for Mobile (GSM) technologies. The system also obtains GlobalPositionting System (GPS) parameters related to the field and sends them to a central monitoring station. This system is expected tohelp farmers in evaluating soil conditions and act accordingly.Key words: Sensors, ZigBee, GPRS, GSM, GPSconsumption, flexible automatic networking temperaturehumidity monitoring system of soil.

free of debugging and almost no outer circuit. The system uses32-bit RISC processor Samsung S3C2440 with variousfeatures and peripherals. It’s based on ARM 920T core andsupports embedded Linux, WinCE, VxWorks and otherembedded operating system. All the properties meet therequirements of the remote monitoring system.3) Humidity sensorumidity measurement instruments usually rely onmeasurements of some other quantity such as temperature,pressure, mass or a mechanical or electrical change in asubstance as moisture is absorbed. By calibration andcalculation, these measured quantities can lead to ameasurement of humidity.4) Soil sensorThe soil sensors collect information on soil temperature andsoil moisture in the outdoors environment.Figure. 1.

Zigbee communication protocol realizingThe digital frequency part, the direct sequence spreadspectrum (DSSS) technology, not only can easilyrealize 802.15.4 short-range wireless communicationstandard compatible, and greatly improve the reliability ofwireless communications10. The protocol stack design isprecise and reliable, including very important logy, etc4.In the past, due to the low consumption, we more usedstar topology in the networking. But the coverage and theefficiency will be limited by the structure of the network bystar, and failure of Cluster nodes can lead to the failure of thenetwork structure. Relative to the star network, the scopepreventing ordinary lithium battery power supply time shortand cannot continue ,making a foundation for using the treetopology. of physical of tree network is bigger, the numberof nodes for more.
