摘要
For instrument multifunction, this article introduces a new multi-parameter environmental monitoring instrument. This article chooses the electrochemistry gas sensor as signal acquisition element which has the characteristics of small volume, high sensitivity. Using a single crystal designed as PM2.5 detection module. It can measure SO2, NO2, CO, H2S and PM2.5 meanwhile. It simply and exactly achieved the measurement of every parameter by designing related circuits. The communication between computer and Labview was realized by serial port. This instrument has high accuracy, small volume, and higher performance price ratio and so on.
