Design and Implementation of Environment Monitoring System Based on ZigBee

ZigBee technology with the characteristics of low complexity, ad-hoc network, low cost, low power consumption and high security, is widely used for wireless sensing. Wireless sensor network is an interdisciplinary application between multi-sensor technology and wireless network, and has the broad application prospects in many fields such as intelligent agriculture and smart home. This paper designs and realizes an indoor environment monitoring system based on ZigBee and wireless sensor network. The system uses end-nodes to collect temperature, humidity, PM2.5 and other environmental parameters. The collected data is transmitted to the coordinator through wireless sensor network and finally to the monitoring system software by serial port protocol. The online monitoring platform with functions of real-time data display, storage and over-limit warning is developed by using the LabVIEW software. The test results show that the system is stable, easy to generate a network system, speedy and reliable to transmit data, and flexible to place nodes.
