摘要
针对传统土壤温度测量方法的缺陷,设计了一种以16位单片机MSP430F149为主控制系统的土壤温度检测系统。在测量时将整个传感器节点埋入土层长期监测土壤温度,通过无线通信芯片nRF905以无线方式进行数据传输,解决了传统测量方法中劳动强度和测量准确性不能兼顾的矛盾。该系统运行速度快、传输距离远、精度高、功耗低。
In view of the disadvantages of traditional soil temperature measurement,a new soil temperature monitoring system was designed with a 16 monolithic integrated circuit MSP430F149 as the primarily control system.The lower labor intensity and higher survey accuracy in traditional measurement could be both resolved by collecting long-term temperature data from sensor that buried in soil and transferring data from wireless communication chip of nRF905.The results showed that this high accuracy and low power loss system could run fast and transmit data from long distance.
