SparkFun MEMS Microphone Breakout – INMP401 (ADMP401) (Via Sparkfun)

Technical description: MEMS microphones work the same way as most condensor microphones; however, they operate on the micro-scale. Microphones are usually used to monitor sound activity, but can also be used to trigger events based on audio cues.

Limitations: Microphones can pick up sensitive information and generally raise suspicion when used to monitor speech. These microphones have a limited frequency range, up to 15kHz, within the human range of hearing. This may result in aesthetically disappointing audio quality if used for musical purposes.

Skill: Beginner
