Electret Microphone - 20Hz-20KHz Omnidirectional

The Electret Microphone Capsule is a compact omnidirectional microphone with a 20Hz–20kHz frequency response, making it ideal for audio sensing, sound detection, recording, and voice-reactive electronics projects.

This electret capsule microphone is the same one we use in our great microphone amplifier board. It contains a small vibrating element that will output a few millivolts peak-to-peak. You will need an op-amp to amplify the signal, some chips are designed with the amplifier built-in in which case you can wire it up directly. This is an "omnidirectional" microphone, with -44dB sensitivity, and has 20-20KHz frequency response. You can plug it into a breadboard or perfboard or solder wires to the little wires sticking out the back. Check out OpenMusicLab's great tutorial on Electret Microphones for a deeper look at how these sensors work. Features
