Perfect for voice-activated projects
This module works flawlessly with my Arduino Uno. The sensitivity adjustment is very precise, allowing me to filter out background noise effectively. Great value for the price.

Reliable component for student projects
We bought ten of these for our university robotics club. They are consistent and durable. The digital output makes interfacing with microcontrollers very simple.

Great for smart home prototypes
Used this to create a clap-switch for my living room lights. It responds instantly and hasn't given any false triggers since I tuned the potentiometer.

Solid performance
Works as advertised. The build quality is decent for the cost. Just make sure you provide a stable 5V supply for best results.

Good sensitivity, easy to use
Setup was straightforward. It detects claps and whistles reliably. I deducted one star because the documentation could be more detailed regarding voltage limits.

Exceeded expectations
I was worried about noise interference, but this module handles it well. The LED indicator is bright and helpful for debugging code.
Q: Is this waterproof or suitable for outdoor use?
A: No, this module is not waterproof. It is designed for indoor use or must be placed inside a protective enclosure if used outdoors.
Q: Can I power this directly from a 3.3V pin on an ESP32?
A: Yes, the operating voltage range is 3.3V to 5V, so it is fully compatible with 3.3V logic systems like the ESP32.
Q: Does this module output analog or digital signals?
A: This specific model outputs a digital switching signal (HIGH/LOW). If you need analog amplitude data, please check our ASR series modules.
Q: What is the maximum distance it can detect a clap?
A: Detection distance depends on ambient noise and sensitivity settings, but typically it can detect a sharp clap from 3 to 5 meters away in a quiet room.
Q: How do I adjust the sensitivity?
A: There is a blue potentiometer on the board. Turn it clockwise to increase sensitivity and counter-clockwise to decrease it while testing with your code.
