我们已经将MQ2用于烟雾传感,MQ-135用于空气质量监测项目。在这里,我将使用sainsmart的MQ-137传感器来测量氨(以ppm为单位)。有了传感器,我浏览了所有可用的教程,发现没有关于如何以ppm为单位测量气体的适当文档。大多数教程要么只处理模拟值,要么介绍一些常数,这些常数对于测量所有类型的气体都不可靠。因此,在网上摆弄了...
8.3.4.4 Smoke sensor MQ2 gas sensor is an electronic sensor used for sensing the concentration of gases in the air, such as liquefied petroleum gas (LPG), propane, methane, hydrogen, alcohol, smoke, and carbon monoxide. MQ2 gas sensor is also known as a semiresistor. This sensor works on...
