Okdo Sound Sensors, Analogue Output, 5V

The Okdo TelePort sound sensor, aiming at the detection of the sound intensity. Based on the LM386 amplifier, it can amplify the detected sound. Then the Arduino will sense it and turn sound signals into the the analog signals, that is, the voltage value by feedback can demonstrate the sound intensity. In addition, the blue potentiometer is used to adjust the sound intensity.

Compatible with RJ11 6P6C OKdo TelePort Control boards and expansion shields
Used for detecting the ambient loudness in an environment
Make interactive circuits such as a voice-operated switch
