Abstract: Aiming at the problems of creating a wired network,such as heavy workload with a lot of wires,an influence to cultivation and irrigation,wireless sensor network(WSN) technology was used in precision agriculture crop growth environment monitoring system.High performance and lowpowered JN5148 was adopted as the main processor chip.The sensor nodes of soil humidity,temperature, PH, solar radiation, router, coordinator were built. The communication between coordinator and upper monitor was accomplished with OPC interface programming technology .Precision agriculture crop growth environment monitoring system was composed by ZigBee wireless sensors.The results indicate that this system worked properly which verified the rationality of the design and development.The system can also achieve the collection and transmission of the crop growth environment in the monitoring area.

 

Key words: precision agriculture; wireless sensor network(WSN); OPC; coordinator
