Indoor Environment Detection System Based on ZigBee
Abstract:With the continuous improvement of people's living standards, people's demand for indoor environmental quality has become increasingly high. This paper is based on the current domestic home environment monitoring the development of the status of the design of a CC2530 based on the indoor environment testing system. The system uses the wireless sensor module with CC2530 as the core to realize point-to-point communication. The parameters and data of the environmental parameters are accepted and forwarded by the coordinator. The sensor nodes carry out the measurement and forwarding of the environmental parameters. The host computer software displays and detects the environmental parameters. This paper mainly discusses the technical background of the related ZigBee wireless sensor network module with CC2530 chip as its core, which is based on the IEEE802.15.4 standard, its protocol architecture, technical characteristics and the basic way of realization [1]. The hardware The feasibility of the design realization. And the design and use of the temperature and humidity sensor module, smoke sensor module, the human body sensor module and OLED display module for a brief description and analysis. This article also briefly describes the design of the host computer software. Finally, the functional effects of temperature and humidity, smoke and human induction are tested and simply authenticated, and the results are analyzed and summarized. Experiments show that this design structure is very simple, easy to use and operation, the function is more complete, in reality has a certain practical value.
