摘要
采用数字式温湿度传感器SHT11、单片机MSP430和ZigBee无线收发芯片设计完成了一种分布式无线温湿度测量系统。采集节点通过单片机采集和处理温湿度信息,通过ZigBee实现数据的自组网传输。通过样机测试,系统在室内100 m范围内能可靠传输,室外可达1.5km以上,具有很强的实用性和广泛的应用领域。
The distributed wireless temperature and humidity test system was designed by using digital sensor SHT11, SCM （Single Chip Microcomputer） MSP430 and single chip transceiver ZigBee. The temperature and humidity data was acquired by SCM for processing and automatically through the ZigBee network for data transmission. Through testing, the distance of transmission indoor was about 100 meters, up to more than 1.5km outdoor. This system had a high practicality and broad area of application.
