Application of ZigBee in Monitoring System of Crop Planting Environment DAI Yuan YANG Long HE Dong-Jian （Northwest A & F University, Yangling, Shannxi, 712100,China） Abstract:According to our country’s agriculture with the characters of farness、disperse、 inconstancy、and multiplicity, this paper proposed a kind of design proposal of wireless sensor network based on ZigBee technology. MCU PIC18LF4620 and RF module CC2420 are used to establish the sensors network . The system adopts the algorithm of AODV to slove the problem of routing. Finally, a monitoring system of low-complication 、low-cost and low-power is implemented. It satisfies the demand of real time monitoring system of crop planting environment by monitoring temperature、humidity、illumination and other information. It has practicality value.
