Home Security System Design And Test Based On STM32

The smart home security system is a reliable and effective home system for intelligent environment detection and security monitoring.With the development of social technology,it has rapidly spread and is increasingly used in people's residential design as a home environment.An important hub for monitoring,it can achieve high-precision temperature,humidity and other aspects of detection,its excellent performance can meet the needs of the escalating new residential,and realize its practical value.In this paper,a combination of embedded systems and Internet of things designed a smart home security system and remote human-computer interaction interface.The design of the system is divided into intelligent home security system and remote human-computer interaction interface two parts.The design of the intelligent security system is mainly based on STM32F103 series development board,it can monitor the home environment in real time by the using of temperature sensors,human infrared sensors and smoke detection sensor,achieve real-time displaying of environmental conditions through the LCD,and send warning messages to the user's mobile phone through the SMS function of GSM module when the system detects abnormal signal to improve the safety index of living.The remote human-computer interaction interface is transmitting the data by the MCU to the cloud platform through the W5500 Ethernet control module.Users can access the yeelink cloud platform wherever they can connect to the network to monitor the environment parameters of house.This clever use of embedded systems and Internet of Things technology in the system provides a way for the design of the smart home system in today's society.Its low-cost,low power consumption,high-performance features make smart home security system entering more family and community hopefully,the system in the smart home security market has great prospects for development.
