【摘要】 针对家庭网络的特点以及室内环境监测的要求,系统利用无线传感网络中ZigBee技术的低功耗、低成本和低复杂度等特点,用CC2530芯片、SHT11温湿度传感器及MQ-2气体传感器等节点,在ZigBee2006协议栈的基础上开发出家居终端监测系统。系统利用终端节点将采集的数据上传至协调器,协调器将数据发送到上位机,上位机可实时显示环境数据供用户观察。实验表明,利用ZigBee技术可降低系统复杂度并节约成本,实现对终端的区域化灵活控制。更多还原

【Abstract】 According to the characteristics of the family network and the requirements of the indoor environment monitoring, the home terminal monitoring system based on ZigBee2006 protocol stack is developed by using CC2530 chip, SHT11 temperature and humidity sensor, and MQ-2 gas sensor, etc. The ZigBee technology in wireless sensor network has such characteristics as low power consumption, low cost, low complexity, etc. The system uses terminal node to upload the collected data to the coordinator, and then the data is sent to the PC by the coordinator. The PC can display in real time the environmental data and users can observe them. The experimental results show that ZigBee technology can reduce the system complexity and cost, and control the regional terminal flexibly.更多还原
