Design and Realization of Indoor Air Odor Control System Based on STM32 Single Chip Microcomputer

With the design and realization of indoor air odor control system as research objective and based on the brief introduction to a detection control system at home and abroad and its development trend, this study introduces sensor technology to the main indoor air odor (formaldehyde and ammonia gas) and air temperature and humidity which seriously threaten people's health. On the basis of a brief analysis of the overall structure of the indoor air odor control system and the detailed design of the system's lower electro-mechanical circuit and system software, this study sets up an indoor air odor control system with PC as platform and STM32 single chip microcomputer as core. The test of the system shows that the system can realize real-time monitoring of indoor air odor, temperature and humidity, and can get the overall quality level of indoor environment, with certain feasibility and practical value.
