基于单片机的酒精浓度检测仪设计

Design of Alcohol Concentration Detector Based on Single Chip Computer

以单片机和气体传感器为核心,设计了酒精浓度检测仪,实现了不同环境下酒精浓度的检测。本文主要介绍了酒精浓度检测仪整体结构,设计了系统硬件电路,阐述了各模块功能并着重研究了气体传感器的选择。

an alcohol concentration detector is designed taken single chip computer and gas sensor as kernel. The alcohol concentration in different environment can be measured. In this paper, the whole construct of the alcohol concentration detector is introduced; the system hardware circuit is designed; the function of each model and how to select the gas sensor are discussed especially.
