Study & Design on Monitoring and Controlling System for Greenhouse Group Based on ZigBee

It is very important for the development of planting in greenhouse to control the greenhouse environment in group by computer. Aiming at the defects of complex wires,low expansibility and maintainability,the author raises a solution based on the wireless communi- cation technology called ZigBee,which helps us connect the controllers in all of the greenhouses and the central computer in a wireless network.That makes the controlling system more reliable and flexible,especially;it is low-cost and consumes less power.The system is designed with the module JN5121-DK103 and ZigBee's software topology structure in tree form.
