Hai, i have a problem with my project. I have a MQ-136 module sensors, but i don't know how to calibrate and get a right ppm to detect a H2S gas level. Please help me,please help my project. This is for my final project
Do you have that standard concentration of H2S gas to use? And do you have a vessel that can be filled with that gas? Can you put your sensor with the wire connections in that vessel?
