In recent years, In recent years, global warming is on the rise with the emissions of greenhouse gas.The estimate about the carbon sink of farmland ecosystem is important to study its effect on global warming and have effectively control to greenhouse gas emissions.This paper focuses on the use of ZigBee wireless sensing technology, which can acquire relete impact factors quickly.In addition, this paper introduces some carbon sink impact factors and the design of hardwareand software about some nodes in the Zigbee wireless sensing network.
