Abstract
An online environmental monitoring system based on ZigBee wireless sensor network is designed to overcome the drawbacks of the traditional indoor environment monitoring system, such as the difficulty of wiring and the poor flexibility. The ZigBee communication technology, web server technology and GSM communication technology are synthesized, and the indoor temperature and humidity, carbon monoxide, formaldehyde concentration and other environmental information are collected and monitored in real time by various supporting sensors. Users can complete local and remote real-time monitoring of indoor environment by opening Web pages. When a fire or gas leak occurs, users will receive alert messages in time. Experiment show that the system has the advantages of stable operation, simple use and good flexibility, and has high practical value and wide application prospects.

With the development of the times, a safe and healthy living environment has become a goal pursued by more and more people
ZigBee is a wireless network protocol based on the IEEE802.15.4 standard. It is a short-distance, low-power wireless communication technology, which is characterized by close range, low complexity, selforganization, low power consumption, low data rate, and low cost, suitable for the construction of indoor environment monitoring network [2-4]
In order to verify the practicability of the system, an indoor environment monitoring and early warning system based on ZigBee network was established
Summary
With the development of the times, a safe and healthy living environment has become a goal pursued by more and more people. ZigBee is a wireless network protocol based on the IEEE802.15.4 standard. It is a short-distance, low-power wireless communication technology, which is characterized by close range, low complexity, selforganization, low power consumption, low data rate, and low cost, suitable for the construction of indoor environment monitoring network [2-4]. This paper uses ZigBee network technology, mobile terminal technology and GSM communication technology to design an indoor environment online monitoring and early warning system. The system sends an alarm message to the user in time. This system overcomes the limitations and regionality of traditional methods, and has the advantages of simple use, strong flexibility and good real-time performance
