Description
The Arduino Sound Sensor Module is a versatile device expertly designed for detecting sound waves by converting them into electrical signals. Ideal for Arduino projects, this sound detection sensor is highly effective when sound surpasses a predefined threshold, providing both digital and analog output. This sensor sound integrates a condenser microphone and an LM393 op-amp, featuring an adjustable set point via an onboard potentiometer. When the sound intensity crosses the set point, an onboard LED lights up, sending a low output signal. With its user-friendly 3.3V-5V operating voltage, the sensor with sound is perfect for numerous sound detection applications.

How to Use
To use the Arduino sound sensor module, connect it to an Arduino board. Utilize the VCC, GND, and OUT pins on the sensor for connections. Use a breadboard and jumper wires to connect the sensor's VCC to the Arduino's 5V or 3.3V pin, and GND to the Arduino's ground. Connect the OUT pin to a digital pin on the Arduino for simple HIGH/LOW detection when sound crosses a threshold or use the Analog Output (AO) for more precise sound level monitoring by connecting it to an analog input pin. The sensor with sound can be adjusted with the onboard potentiometer to set your desired sound level threshold. Surpassing this threshold will activate the LED, and the OUT pin sends a LOW signal. This configurationsupports various Arduino sound sensor projects, including voice detection, by loading suitable programs onto the microcontroller.
