About this product
A sound detection module built around an LM393 comparator and an electret condenser microphone. It gives a digital output when a sound is detected, suiting clap switches, noise alarms and simple sound-triggered projects with Arduino. The single-channel output is active low, and an indicator LED shows the signal state.

Can I connect it directly to an Arduino?
Yes. Power the module at 3.3V to 5V DC, connect GND and VCC, and wire the digital output to a digital input pin. The output goes low when sound is detected.
Does the output show how loud the sound is?
No. The output is a single digital signal, so it indicates whether sound was detected, not its volume level. For loudness measurement you would need an analog sound sensor.
