Clap switch works well
Using it for a home automation prototype. Response time is quick and the LM393 comparator provides a clean signal.

Exactly as described
Blue PCB matches my other sensor modules nicely. Compact size makes it easy to fit into small enclosures.

Sensitive but needs tuning
Had to adjust the potentiometer carefully to avoid false triggers from background noise. Once set up, it works reliably.

Good but fragile
One pin bent during shipping, but I was able to straighten it. Functionality is fine otherwise. Packaging could be more protective.

Great for DIY projects
Works perfectly with my Arduino Uno. I used it to create a simple clap switch for my desk lamp. The sensitivity adjustment is very useful.
Q: Does it come with header pins soldered?
A: Headers are not included by default. You will need to solder your own pins for breadboard or PCB connection.
Q: Is there an analog output available on this module?
A: This specific module provides a digital switching output. For analog sound levels, you would need a different microphone amplifier board.
Q: Does this work with 3.3V logic boards like ESP32?
A: Yes, the module operates within DC 3.3V to 5V, making it compatible with ESP32 and similar boards.
Q: Can it detect specific frequencies like a whistle?
A: It detects sound intensity rather than specific frequencies. A sharp whistle usually triggers it due to the sudden increase in volume.
Q: What is the effective detection range for a clap?
A: Range depends on ambient noise and sensitivity settings, but typically works within 1 to 3 meters in a quiet room.
