摘要
该设计是基于Arduino的室内环境检测系统。以单片机为核心,采用MH-Z16传感器对CO_(2)浓度进行测量,采用PM2.5传感器对PM2.5浓度进行测量。再将模拟信号转化为数字信号以便于Arduino板进行数据分析并处理,再用LCD1602液晶显示屏显示出来。若检测值超标,系统则将发出警报,并且通过新风系统调控室内相关参数浓度,使参数恢复到正常指标。本设计的优点在于成本较低,可靠性强,功耗小。
This design,indoor environment detection system,is based on Arduino.The whole system is based on Single-Chip Microcomputer.MH-Z16 sensor is used to measure CO_(2)concentration and PM2.5 sensor is used to measure PM2.5 concentration.Then the analog signal is transformed into digital signal,which is analyzed and processed by Arduino board,and displayed by LCD1602.If the detection value exceeds the standard,the system will give an alarm,and the microcomputer will control the central ventilation system to reduce the concentration of indoor relevant parameters,making the parameters reach the normal index.The advantages of this design are low cost,high reliability and low power consumption.
