基于单片机的室内粉尘与异味检测系统设计

摘要

为满足对室内空气质量的实时监测,保护人体健康,设计一种基于单片机控制的室内空气质量检测系统.该系统以 STM8S903K3 单片机为核心,利用粉尘与异味传感器检测室内粉尘与异味的浓度,当浓度超标时发出警报;具有低功耗、小型化、高精度、灵活性强等特点,可用于不同环境下对空气质量进行实时监测,是一种便捷实用的室内空气质量检测工具.%In order to satisfy the real-time monitoring of indoor air quality and protect the personal health, this paper designs an indoor air quality detection system based on single-chip microcomputer with STM8S903K3.The concentration of dust and odor is detected by the sensors. If threshold exceeding the setting space it will set on the alarm. This system supplies a convenient and practical method for indoor air quality testing, which has low power consumption, small structure, high precision and flexibility. Generally, it is practically useful in real-time monitoring air quality under different circumstances.
