A Portable Environmental Parameter Monitor Based on STM32

In this paper, a portable monitoring system with environmental parameters as breakthrough point is proposed, and focuses on the research and development of a portable instrument for monitoring the quality of indoor environmental parameters. This paper studies and designs a portable environment parameter detector based on STM32 development board, which collects monitoring data through external sensors. Write your own based on STM32 platform of data acquisition and processing procedures, the successful implementation of the, temperature, humidity, formaldehyde, CO, real-time monitoring of environmental parameters such as methane, and through the LCD screen display in real time. Testing environment parameter meter, real-time display of the corresponding data and collecting sample data processing analysis of a day, to achieve the desired goal.
