基于MQ-7传感器煤气报警系统

为了能够实时监控室内天然气泄漏情况,采用半导体MQ-7传感器为数据采集元件,以AT89S52单片机为主控制核心,设计了一种天然气报警系统。系统根据环境状况作处判断,自动开启排气装置和语音报警装置,实现了自动报警、自动处理警情、自动检测全过程自动化。具有实时跟踪显示室内天然气浓度,实时监控天然气泄漏。经Proteus软件仿真表明,该系统可快速准确的检测被测气体中CO浓度,硬件部分具有可靠性高、实用性强、便于扩展等优点。

Gas Alarm System Based on MQ-7 Sensor

In order to be able to real-time monitoring of indoor gas leakage, using MQ-7 semiconductor sensor for data acquisition components, with AT89S52 single chip as the control core, a gas alarm system is designed. The system according to the environmental conditions makes judgment, automatically open the exhaust device and a voice alarm device, automatic alarm, automatic processing, automatic detection alarm automation of the whole process. The system has real-time tracking display the indoor gas concentration, real-time monitoring of natural gas leakage. The Proteus software simulation shows that, this detection system can quickly and accurately measure CO concentration in air, the hardware has the advantages of high reliability, strong practicability, easy to expand etc..
