Abstract:  In view of the current shortage of agricultural water and the low utilization rate of irrigation water, a water-saving irrigation system based on ZigBee wireless sensor network is designed. This system takes embedded microprocessor S3C2440 as the control core, uses CC2530 to build ZigBee wireless network, collects the soil moisture by sensor nodes distributed in the field, uses ZigBee network to realize wireless transmission of data and instruction. According to the soil moisture content and the threshold value of the soil moisture, the opening and closing of the electromagnetic valve node can be controlled to realize the water-saving irrigation. The experimental results show that the measuring points placement of the monitoring system is flexible, the data communication is smooth and effective, the operation is stable and reliable, and all expected design objectives have been achieved.

Key words: water-saving irrigation, sensor network, embedded gateway, ZigBee, CC2530
