Great for learning
Used this for my final year project. Documentation online is helpful and the pinout is standard for most microcontrollers.

Perfect for Arduino Clap Switch
Works flawlessly with my Uno board. Sensitivity adjustment is easy using the onboard potentiometer. Great value for money.

Fast Response
Detection speed is impressive. Using it for a voice-activated LED project and the latency is negligible.

Good value
Solid module. Had to tweak the potentiometer to stop false triggers from background noise, but once set, it works well.

Sensitive to noise
Works well but picks up background noise easily if gain is maxed out. You need to find the sweet spot for calibration.
Q: What is the detection range?
A: The effective range depends on ambient noise and sensitivity settings, typically up to 2 meters for loud claps.
Q: Is there a specific library for this?
A: No specific library is needed. It functions as a simple digital input pin read using standard GPIO functions.
Q: Does this output analog or digital signal?
A: This module provides a digital switching output. For analog audio waves, you would need a different microphone amplifier module.
Q: Can I use this with 3.3V logic?
A: Yes, the operating voltage range is 3.3V to 5V, so it is fully compatible with 3.3V systems like ESP32.
Q: Can it distinguish between whistle and clap?
A: The module detects sound intensity, not specific frequencies. You would need additional coding to differentiate sound patterns.
