摘要
本设计利用MQ-3型气体传感器与单片机AT89S52实现了对不同酒精浓度的测量,并对测量结果进行数据分析及显示,同时利用发光二极管亮灭来显示浓度的高低,并设定浓度阈值,如果测试结果超过设定值时发出报警。
The MQ-3 gas sensor and single chip AT89 S52 are used to measure different alcohol concentration. At the same time the concentration is analysised and displayed.Meanwhile, the LED is used to show the concentration. And the concentration threshold is set, if the test results exceed the set value,it sends an alarm.
