【原理介绍】

        MQ-2气体传感器所使用的气敏材料是在清洁空气中电导率较低的二氧化锡(SnO2).当传感器所处环境中存在可燃气体时,传感器的电导率随空气中可燃气体浓度的增加而增大.使用简单的电路即可将电导率的变化转换为与该气体浓度相对应的输出信号.MQ-2Gas sensor for liquid gas、丙烷、The high sensitivity of hydrogen,For natural gas and other combustible vapor detection is ideal.这种传感器可检测多种可燃性气体,是一款适合多种应用的低成本传感器.封装好的气敏元件有6只针状管脚,其中4个用于信号取出,2个用于提供加热电流.基本电路如图.
