Great for student projects
Bought a bulk pack for our university lab. Students find them easy to use for sound detection assignments. They are durable enough to handle repeated plugging and unplugging on breadboards.

Excellent sensitivity
I was surprised by how sensitive this little board is. Even a soft whisper can trigger it if you turn the dial up. I'm using it for a home automation light switch project and it performs perfectly.

Solid component for the price
Works as described. The LM393 comparator is reliable. My only minor critique is that the silk screen printing is slightly faint, but the pinout is standard so it wasn't an issue. Happy with the purchase.

Easy to integrate
Plug and play with standard microcontroller libraries. The digital output makes coding very simple compared to analog modules. Shipping was fast and the item arrived well-packaged.

Good sensor, needs calibration
The build quality is solid and the pins are well-soldered. It took a little time to get the potentiometer setting just right for my room environment, but once calibrated, it triggers reliably. Would recommend.

Perfect for voice activation projects
This module works flawlessly with my Arduino Uno. The sensitivity adjustment is very responsive, allowing me to tune it specifically for clapping sounds without picking up background noise. Great value for the price.
Q: Can I power this directly from a 9V battery?
A: No, the operating voltage range is 3.3V to 5V DC. Connecting it directly to a 9V source may damage the comparator chip. Please use a voltage regulator or a 5V power supply.
Q: What is the maximum distance it can detect a clap?
A: Detection range depends heavily on ambient noise and the sensitivity setting. In a quiet room, it can typically detect a sharp clap from 3 to 5 meters away.
Q: Does this module output analog or digital signals?
A: This specific model outputs a digital signal (HIGH/LOW). If you need analog output to measure sound intensity levels, please look for our analog microphone sensor variant.
Q: Is the connector included or do I need to solder headers?
A: The module comes with the pins pre-soldered. However, the PH2.54 cable connector is usually not included unless specified in the bundle options. You may need to solder your own wires or buy jumper cables separately.
Q: Will this work with a Raspberry Pi Zero?
A: Yes, it is fully compatible with Raspberry Pi models including the Zero. Just ensure you connect the VCC pin to the 5V or 3.3V GPIO header and the DO pin to a GPIO input pin.
