Instructions:

1. Power Supply: Connect the VCC pin to a power supply between 3.3V and 5V, and GND to ground.
2. Signal Connection: Connect the DO (Digital Output) pin to your microcontroller’s input pin for detecting sound events.
3. Adjust Sensitivity: Use the onboard potentiometer to adjust the sensitivity of the sensor according to your application needs.
4. Mounting: Secure the sensor in a location where it can effectively capture sound without obstruction.
5. Testing: After setup, test the sensor by generating sound near it and observing the output signal change on your microcontroller.

Ensure that the operating voltage and connections are correct to prevent damage to the sensor.
