Accurate measurement of soil moisture is the basis of water saving irrigation and precision agriculture. In order to achieve soil moisture by the means of automatic measurement and wireless transmission, wireless soil moisture sensor node based on FDR and CC2530 chip is designed. FDR can achieve data rapidly and accurately and CC2530 implements ADC, digital signal processing and RF transmission and so on. The problem of power consumption of the node is discussed, and the packet loss rate is tested. The results show that the design and development of the sensor node based on CC2530 has the characteristics of low packet loss rate, stable operation and reliability. It can meet the requirements of the wireless data acquisition of soil moisture.
