【摘要】 利用半导体气敏传感器MS1100采集甲醛气体,STC单片机对电压信号进行模数转换并发给Hi-Link的RM04模块,通过无线网络传输给上位机;上位机的Lab VIEW程序对数据进行接收处理和图形表达.多个气体采集节点构成星型网络,可对一定范围内环境气体进行监控.更多还原

【Abstract】 Voltage signal is from semiconductor gas sensor MS1100 to gather Formaldehyde gas that STC SCM convert analog signal to digital,and pass on the Hi-Link’s RM04 modules to PC by means of wireless network; Lab VIEW programs to PC data processing graphic expression.Many gas collecting nodes are constituted of star neenork,which can monitor the ambient air within a cerain range.更多还原
