Hi, i have two sound sensor boards, both don't work very well. I even placed those near the speaker playing heavy metal, but they gives me the analog readings no more than 50. I have to blow directly at the mic of the modules to get the reading larger than 100. But no matter how I hard I blow, the reading is no larger than 600. And they definitely not quite response to my clapping. So I wonder is there any way to increase the sensitivity of sound sensor? I already did turn the potentiometer all the way anti clockwise to get those readings.
Thank you!
