摘　　要：MQ系列气体传感器是工程上测试气体浓度的一种常用传感器。由于该系列传感器采用金属氧化物半导体作为敏感材料,因此需进行开方或对数运算才能最终得到被测气体浓度,这对单片机来说并不容易。为此从工程应用角度出发,推导了一种数据处理算法,并经工程实际应用验证,以期为相关人员提供参考。MQ series gas sensor is a commonly used sensor for testing gas concentration in engineering projects.Because this series of sensors use metal oxide semiconductors as sensitive materials,it is necessary to perform square root or logarithmic calculations to finally obtain the measured gas concentration,which is not easy for MCU.For this reason,from the perspective of engineering application,a data processing algorithm is deduced and verified by actual engineering application,in order to provide reference for relevant personnel.
