  • Design of Smoke Alarm Device Based on STM32C8T6 Single-chip Microcomputer

    Open Access

    Abstract: At present, with the popularization of high-power electrical equipment, more and more fires occurred. In order to protect the safety of people’s lives and property, the prevention and monitoring of fires has become an urgent problem in today’s society. The system is a single-chip microcomputer smoke alarm system designed for schools, families, hotels, cinemas, office buildings and public places. It uses STM32C8T6 single-chip microcomputer as the controller. When the device detects signals through the MQ-2 smoke sensor, then inputs the signals to the single-chip microcomputer after A/D conversion. And the buzzer is also controlled through the single-chip microcomputer to realize the smoke alarm. The system has the characteristics of high reliability, low cost, and easy maintenance.
