摘要/Abstract

摘要： 为实时监测室内 CO2 浓度变化, 以 STC89C52 单片机为核心, 设计了一种基于气体传感器的二氧化碳报警器。硬件系统包括二氧化碳传感器、信号调理电路、模数转换电路、 STC89C52 单片机和声光报警单元。软件系统包括数据采集、数据处理、报警逻辑等功能单元。该报警器在室内 CO2 体积百分比超过1. 5% 时可以及时启动声光报警功能, 并可实时显示室内 CO2 值。

关键词: 气体传感器, 单片机, 报警器

Abstract: To monitor changes of indoor carbon dioxide concentrations in real time, a carbon dioxide alarm based on a gas sensor with a STC89C52 microcontroller as the core is designed. When the CO2 concentration in the air exceeds the preset value, the sound and light alarm function can be activated, and the indoor CO2 concentration value can be displayed in real-time. The hardware system includes a carbon dioxide sensor, signal conditioning circuit, analog-to-digital conversion circuit, STC89C52 microcontroller, and acousto-optic alarm unit. The software system includes data acquisition, data processing, alarm logic, and other functional units. The alarm can be activated in time when indoor CO2 concentration exceeds 1. 5% .

Key words: gas sensor, single chip microcomputer, alarm
