My classmate suggested me to use the sound sensor existing in damaged microphone so that I didn't have to waste time and money to buy one on estores. But after I disassembled my microphone, I couldn't find any of such sound sensor. I am embarrassed. Where can I mostly find one in my e-junks ? I need one as small as my fingertip for my school assignment. Thank you.
