The Design And Implementation Of Indoor Environment Monitoring System Based On ZIGBEE Technology

With the development of the wireless network,the quality of people s life increases gradually,life with convenient,simple and security mode is needed in the future.Home is essential for people's lives,a warm home will bring more happiness to people,therefore,the design of an intelligent indoor environmental monitoring and control system is necessary.Zigbee technology is a rapidly developing technology in recent years,Its low power consumption,low cost and low rate,and its unique technology of safety and reliability,make it won the market quickly,it is applied in both industrial and home field.The construction of monitoring system for indoor environment based on zigbee technology,can improve the living and office environment.This design is mainly divided into three parts:the zigbee sensor network part,gateway data transmission part and the terminal part of the PC control.Zigbee sensing network part mainly includes temperature and humidity,gas,CO₂ concentration monitoring node and lighting,air conditioning controlling node.The zigbee is CC2530 module of TI,Using its ad hoc network technical,the design realizes the information transmission between terminal nodes and coordinator,and zigbee nodes and gateway by programming;Gateway data transmission part mainly includes the design of wifi module and the main control board.Wifi module selects the RM04 module of Hailing department,the main control board is the STM32F103 series scm.The design realises the data transmission between zigbee coordinator and android part by programming;The terminal part of upper monitor control mainly includes the programming of android phone.Mainly includes the login,data monitoring,data record and control design,and the realisation of the communication between the android interface and gateway by programmingFinally,the system realizes the control in lighting,air conditioning with the handheld terminal;and it realizes the detection of the indoor temperature,gas,CO₂ concentration,and display it on handheld terminal;and realizes the monitoring of indoor security system and the alarm function using the human body infrared sensor to detect human body information.The test shows that the monitoring system is running well.
