基于单片机的室内有害气体检测系统 - 高效可靠，应用广泛

摘要：

本文提出了一种基于单片机的室内有害气体检测系统。该系统采用了 MQ-135 气敏传感器检测室内空气中的有害气体浓度，通过单片机对浓度进行采集和处理，并将结果显示在 LCD 屏幕上。同时，系统还可以通过蜂鸣器发出警报，提醒用户注意室内空气质量。

通过实验验证，该系统具有良好的稳定性和可靠性。该系统可以广泛应用于家庭、办公室等室内空气质量检测领域。

Abstract:

This paper proposes an indoor harmful gas detection system based on single-chip microcomputer. The system uses MQ-135 gas sensor to detect the concentration of harmful gases in indoor air, collects and processes the concentration through single-chip microcomputer, and displays the results on the LCD screen. At the same time, the system can also issue an alarm through a buzzer to remind users to pay attention to indoor air quality.

Through experimental verification, the system has good stability and reliability. The system can be widely used in the field of indoor air quality detection in homes, offices and other places.

Keywords: single-chip microcomputer; MQ-135 gas sensor; LCD screen; buzzer; indoor harmful gas detection.
