Electret Microphone - Omni-directional

This simple little microphone is omnidirectional, making it great for projects where you want a microphone for audio detection coming from any direction! Just plug into a breadboard or perfboard or solder wires to the 2 leads for sound detection and recording. When sound causes the film inside this microphone to vibrate, it generates a voltage of a few millivolts. You can read this voltage directly or use an Op Amp to amplify the signal. Arduino & Raspberry Pi compatible.
