The nature of agricultural environments presents significant challenges in data acquisition and control (DAAC) that hinders both scientific research and process automation. Recent technological advancements in wireless mesh network systems meet these challenges and open the door to agricultural applications limited only to ones imagination. ZigBee, a wireless standard approved in early 2005, is gaining wide acceptance in home and industry automation, but the characteristics of ZigBee make it an ideal fit for meeting the challenges in agriculture. Devices may be placed hundreds of meters apart. The data and control information is relayed (routed) from device to device allowing very large areas to be covered. These low-cost, low-power consuming transceivers can be battery-operated for up to 5 years. Embedded microcontroller technology allows for easy sensor interface and intelligent programming. This paper provides information concerning the Zigbee specification, its benefits in agricultural use, and explores its implementation in theoretical and actual agricultural environments.
