ZigBee is an emerging wireless network technology, according to china's digital agricultural feature such as remote, dispersion, variability and diversity, the ZigBee-based wireless sensor network for digital agricultural data acquisition is one of the best ways to build the system. In this paper, based on ZigBee wireless sensor network deployment planning principles and the status of our digital agriculture, we study several ZigBee wireless sensor network nodes deployment program for different condition and calculated their largest network capacity, network latency and other parameters, finally proposed a wireless sensor network nodes deployment strategy for digital agricultural data acquisition. This strategy is no specific requirements to the wireless sensor network topology structure, and can support the ZigBee wireless sensor network by random and manual deployment.
