摘要
为了实时、便捷地检测室内空气质量,设计了一种融合多种传感器的便携式室内空气质量监测仪。利用新型光、化学传感器与基于STC89C52单片机的信号处理电路测量湿度、一氧化碳(CO)、细颗粒物(PM2.5)三种影响空气质量成分的初始浓度值,结合误差抑制方法提高测量精度,浓度超过设定阈值进行声光报警,并通过全球移动通信系统(GSM)向特定人员发送检测信息。实验表明,该监测仪能够准确地测量并发出警报,且具有体积小、成本低等优点,可广泛适用于住宅、仓库等场地。
In order to detect indoor air quality in real time and conveniently,a portable indoor air quality monitor integrating multiple sensors is designed in this paper.Using new optical and chemical sensors and signal processing circuit based on STC89C52 microcontroller to measure the initial concentration of humidity,carbon monoxide,fine particulate matter,which affect air quality components,combined with error suppression method to improve the measurement accuracy,concentration exceeding the set threshold for acousto-optic alarm,and send detection information to specific personnel through global system for mobile communications(GSM).Experiments show that the monitor can accurately measure and alarm,and has the advantages of small size and low cost.It can be widely used in residential,warehouse and other sites.
