In view of current low degree of popularity of indoor environment monitoring system and comfort degree testing demands

an indoor environment monitoring system based on cloud computing platform is designed and implemented. The system collects indoor environmental information through multi-sensor based on Internet of things（ Io T） technology

the collected data is stored in the cloud database through wireless sensor networks（ WSNs）. Cloud computing platform uses secondary fusion algorithms to analyze and process on collected data and provide Web services

the user can view the indoor environment in real-time through the webpage or the terminal and get the feedback result. Experimental results show that the system has characteristics of low cost

small power consumption and easy to expand

indoor environment monitoring

statistics and comfort evaluation can be comprehensively carried out

and has good practical value.
