摘要
文章基于MSP430系列单片机设计实现了一款手持式一氧化碳(化学式:CO)检测仪。检测仪选用电化学式CO传感器作为气体浓度采集装置,将其采集的浓度信号以电信号输出,并通过4位数码管实时显示CO气体浓度值,测量精度可达到1PPM。同时可根据需要修改报警值,当浓度值超过报警值时,检测仪发出报警信号。
This paper designs a hand held carbon monoxide(CO)detector based on the MSP430 series of single-chip microcomputers.The detector uses an electrochemical CO sensor as the gas concentration acquisition device,and the concentration signal collected by the detector is output as an electric signal,and the CO gas concentration value is displayed in real time through a 4-digit digital tube,and the measurement accuracy can reach 1 PPM.At the same time,the alarm value can be modified as needed.When the concentration value exceeds the alarm value,the detector sends an alarm signal.
