Abstract
Based on people’s demand for indoor air quality monitoring, an indoor ambient intelligence detection system with STM32F103C8T6 microcontroller as the core controller is designed, which can monitor the current indoor temperature, humidity, suspended particles (PM10) and toxic and harmful gases in the air in real time, accurately and effectively. And the current indoor environment is transmitted to the computer for display through Bluetooth, so as to warn people in time and avoid harm to human health. The system has the characteristics of small size, convenience, reliability and simple operation, and can be widely used in the field of indoor environment detection.
Highlights
Due to the acceleration of industrialization, people have excessively cut down trees, exploited coal mines and other resources, and discharged waste water and gas at will, establishing the rapid economic development on the basis of destroying the natural environment and lacking the protection of the natural environment
Thereby causing people to suffer from various respiratory diseases; When people use coal, natural gas, liquefied petroleum gas, etc. for cooking or heating, gas poisoning is caused by insufficient ventilation or improper operation
A 32-bit microcontroller STM32F103C876 based on ARM Cortex-M3 core is used as the core periphery, which is matched with the suspended particle sensor GP2Y1010AU0F of sharp company, the high-performance digital temperature and humidity composite sensor DTH11, and the formaldehyde sensor MQ138, smoke sensor MQ135 and combustible gas sensor MQ2 of weisheng electronics company
Summary
Due to the acceleration of industrialization, people have excessively cut down trees, exploited coal mines and other resources, and discharged waste water and gas at will, establishing the rapid economic development on the basis of destroying the natural environment and lacking the protection of the natural environment. In China, it is not uncommon for people to suffer from diseases or deaths caused by living in polluted indoor air every year. When the pollutants in the air exceed the standard, it can warn people and create a healthy, safe and comfortable living environment for people. In this system, a 32-bit microcontroller STM32F103C876 based on ARM Cortex-M3 core is used as the core periphery, which is matched with the suspended particle sensor GP2Y1010AU0F of sharp company, the high-performance digital temperature and humidity composite sensor DTH11, and the formaldehyde sensor MQ138, smoke sensor MQ135 and combustible gas sensor MQ2 of weisheng electronics company. This system has the characteristics of small size, convenience, reliability and simple operation, and can be widely used in the field of indoor environment detection
