摘　　要：该文介绍一种基于单片机技术的火灾报警器设计,利用温度传感器和烟雾传感器进行火灾监测。单片机进行数据处理和控制,确保火灾检测结果的准确性和报警功能。温度传感器和烟雾传感器监测环境温度和烟雾浓度,一旦超过设定阈值,传感器将信号传给单片机。单片机处理信号,通过软件算法判断是否发生火灾,从而触发声音报警器和可视警报装置。实验证明,这种报警器能快速准确地检测火灾,并及时触发报警。与传统报警器相比,其结合温度和烟雾传感器提高准确性和可靠性。该设计提供高效的火灾预警功能,提升报警准确性和响应速度,更具实用性和可靠性。This paper introduces a fire alarm design based on MCU technology.Temperature sensors and smoke sensors are used for fire monitoring,and MCU is used for data processing and control to ensure the accuracy of fire detection results and alarm function.Temperature sensors and smoke sensors monitor the ambient temperature and smoke concentration.Once a set threshold is exceeded,the sensors send a signal to the microcontroller.The MCU processes signals,uses software algorithms to determine whether a fire has occurred,and triggers audio alarms and visual alarms.Experiments have proved that this alarm can quickly and accurately detect fires and trigger alarms in time.Compared to traditional alarms,the combination of temperature and smoke sensors improves accuracy and reliability.This design provides efficient fire warning functions,improves alarm accuracy and response speed,and is more practical and reliable.
