Sensitive to electrical noise
Works well on battery power, but noticed some interference when connected to a noisy USB port. Added a capacitor and it stabilized. Good product overall.

Reliable audio detection
I've bought five of these for a classroom project. All of them functioned correctly out of the box. The dual output (analog and digital) is very useful.

Good module, needs calibration
The sensor is responsive but you need to spend time adjusting the pot to avoid false triggers. Once set up, it works great for my automation project.

Perfect for Arduino Clap Switch
Worked exactly as expected. The sensitivity potentiometer makes it easy to tune for my specific room noise levels. Connected it to an Arduino Uno without any issues.

Great value for money
Cheap and effective. I used this to trigger an LED strip with a whistle. Response time is very fast. Shipping was quick too.
Q: Can it detect continuous sound or only peaks?
A: The analog output reflects continuous sound levels, while the digital output triggers based on peak thresholds set by the potentiometer.
Q: Does this work with 3.3V logic?
A: Yes, the module operates comfortably within the 3.3V to 5V DC range.
Q: Is there an analog output available?
A: Yes, this module provides both Analog Output (AO) for sound intensity and Digital Output (DO) for threshold triggering.
Q: What is the detection range in meters?
A: Detection depends on sound volume and environment. Typically, it detects loud claps or whistles within 3 to 5 meters in a quiet room.
Q: Do you provide a library for Arduino?
A: This is a hardware sensor that reads standard signals, so no specific library is needed. You can read it using standard digitalRead or analogRead functions.
