Description Particularly sensitive to the intensity of ambient sound High precision and good universality Working voltage: 3-5V DC 3-Pin anti-reverse cable included The Sound Sensor Module has a built-in capacitive electret microphone which is highly sensitive to sound. Sound waves cause the thin film of the electret to vibrate and then the capacitance changes, thus producing the corresponding changed voltage. View more
