Abstract：With the rapid development of the social market economy, an excellent office environment can enhance the competitiveness of the company and improve the physical and mental health of employees, which is conducive to improving the competitiveness of enterprises in the short and long term. The monitoring of human comfort index, that is, the monitoring of various environmental parameters, is extremely important.In the design, an embedded system development platform equipped with sensor technology is adopted to process the monitored data. Combined with the characteristics of simple and easy maintenance and operation and high flexibility of the embedded system platform, the overall deployment and complexity of the whole system development can be reduced. At the same time, Wi Fi wireless data transmission technology is used with cloud server technology to further improve the transmission and forwarding rate of wireless data. Finally, the real-time visual display of data information is realized through the mobile phone. In the design and implementation scheme of the system function, the STM32 development platform is used as the core to build the application part of real-time collection of office environment data. The collected environmental data will be sent to the cloud server through the wireless Wi Fi receiving module in time. Various real-time field status information collected can be timely transmitted to the monitoring sink node through the wireless exchange channel. The sink node saves the data in the STM32 single chip microcomputers, and then extracts the data and displays it through the OLED display module.
