Focusing on the problem of battery remaining capacity of traditional greenhouse monitor node, a scheme, an improved wireless monitoring of agricultural greenhouses nodes, is proposed based on ZigBee technology. It uses an economic and practical method by designing low power consumptionZigBee wireless monitornode. The design enables it efficiently to address the precise measurement of environmental parameters, node voltage, current and battery remaining capacity which employs CC2530 as master control chip by controlling intelligent managing chip sensor and intelligent battery management chip DS2438 and its peripheral circuit.Experimental proved that system runs stably and data detection accuracy is up to 0.001.
