Product description
Electret microphone with high sensitivity and stable characteristics in a compact format. Suitable for speech pickup, sound detection, and embedded applications in consumer electronics, industrial electronics, and educational projects. The microphone provides an analog output signal proportional to the sound pressure level and is typically used together with a simple amplifier stage or an analog input on a microcontroller, sound card, or DSP.
