Design of Indoor Intelligent Alarm System Based on STM32

Abstract

Nowadays, if indoor accidents are not discovered in time, they are likely to cause major casualties. For example, fires, toxic gases, water leaks in the house, etc. will cause a large degree of damage to the interior. In order to prevent such incidents from happening, STM32-based the indoor intelligent alarm system is of great significance. In the past years, some indoor disasters have been reported from time to time. For example, there were more than 290 incidents of fires and poisoning caused by gas leaks. 86% of them were caused by people's negligence, a seen that the development and design of indoor intelligent there were even more burglaries. More than 350. With the development of indoor alarm systems, the incidence of indoor fires has dropped by 60%, and the incidence of burglaries has dropped by as much as 70%. It can be alarm systems are extremely important. This article uses STM32f407VGT6 as the core indoor intelligent alarm system [1], and measures and detects in the real environment. After comparison and analysis, under the same function, compare the STM32f401 and 51 series single-chip microcomputers as the core system to detect indoor temperature and humidity. Detection [5], and outdoor infrared ranging [6], have higher, more accurate, and reliable measurement results, and a more stable system, which greatly improves energy efficiency.
