摘要
搞要:本文介绍了利用H2S电化学传感器对H2S气体浓度进行精确检测的单片机硬件电路、工作原理及软件实现方法。所选用的H2S电化学传感器及信号电桥放大电路能满足在常温下对H2S气体高精度、宽范围检测的要求;在软件设计时,对数据的处理采用了线性插值算法。另外,该系统还采用了分级报警的方式。
This article describes a SCM circuit by hardware which takes advantage of the precise instrumentation for the consistency of the H2S gas, using the H2S electrochemistry sensor, It could also include the working principle and the achievable method of the software. The selected H2S electrochemistry sensor and the signal electric bridge amplifying circuit can satisfy the requirements of the high accuracy and the width scope instrumentation under the normal temperature to the H2 S gas; in software design, processing uses the linear interpolation algorithm to the data. In addition, this system has also selected the graduation warning method.
