摘要
为了能够对大型粮仓内的温湿度进行监控,采用CC2500射频芯片和SHT11数字温湿度传感器,设计了一种基于MSP430单片机的实用粮仓温湿度检测系统及相关的软硬件结构。该系统利用ZigBee无线通信技术构建了分布式无线传感器网络,通过传感器节点对温湿度数据进行采集和传输,具有组网简单,维护方便,运行费用低等优点,能够实现可靠的无线数据传输。
In order to monitor the temperature and humidity in large-scale granarys, a MSP430-based granary tempera ture-humidity detection system with RF chip CC2500 and digital temperature-humidity sensor SHTll was designed. The Zig Bee wireless communication technology is adopted in the system to establish a distributed wireless sensor network. The tern perature-humidity data is collected and transferred by sensor network nodes. The system has the advantages of simple networ king, convenient maintenance and low operating cost, and works stably to perform the reliable wireless data transmission.
