Design of Intelligent Air Quality Online Monitoring Trolley Based on STM32 MCU

In the process of resource and energy development, fuel combustion and the production and storage and transportation, Some dust particles, formaldehyde, stupid system, carbon monoxide and other volatile, toxic and harmful gases of the pollutants are often released into the environment, It's causing air pollution,Seriously affect or threaten the health and life safety of production and management personnel. Accurate and timely detection of dust particles and toxic gas, which can provide a decision-making basis for environmental monitoring and analysis work.This programme designs an intelligent air quality online monitoring trolley system based on STM32 microcomputer,it includes two parts: intelligent tracking obstacle avoidance car control system and air quality detection system.The small car can move forward in the road geographical environment,in the process of reasonable and effective obstacle avoidance, it can detect the quality of air components, conduct real-time data transmission and issue an alarm, and use the wireless transmission module to send the information to the cloud platform to realize the real-time monitoring, transmission and alarm of air quality information. After the test, the system is stable and efficient, which has certain practical value and significance for the research and exploration of the current working environment protection.
