Design of intelligent home safety protection system with STM32

The existing home safety protection systems can effectively monitor various indicators of home environment. However, the systems have difficulties in terms of autonomous rescue and human-machine interaction. To address these issues, we propose an intelligent home safety protection system via STM32. We use STM32F103 as the core component and utilize data acquisition module (DHT11 temperature and humidity sensor, MQ2 and MQ7 gas sensors), relay control module, remote check module (ESP8266 communication component), interactive alarm module (improved SIM800C communication component), and data display module to achieve the monitoring, interaction, and autonomous rescue of the home environment. The results show that the proposed system can effectively monitor the various indicators in real-time, and has these advantages of easy operation, autonomous rescue, and human-machine interaction.
