Microphone sensor isn't working

Other Hardware Audio

Hi,

I'm an arduino newbie. I don't have much experience with circuits.

I just purchased this microphone sensor: http://www.amazon.com/gp/product/B00BOM93VK/ref=oh_details_o00_s00_i01?ie=UTF8&psc=1

I would like to capture the analog output, so I connected the VCC/Ground/Analog pins to the board. The reading I'm getting is always pretty much constant, no matter how close or far I shout into the microphone. I can change the reading using the potentiometer to be roughly in the middle (~512) but I can't get it to fluctuate as I would expect if I'm making noises. If I tap the microphone the values do change quite a bit however.

Is this a bad microphone or am I doing something silly? The unit comes with sound threshold detection which seems to be working which is why I'm confused about the relatively constant analog values.

Any input is appreciated, thanks!

It sounds like you have it working to the best of its ability. Do you trust a company that confuses sensitivity with sensibility? I would not.
It is just not sensitive enough.
