Great sensitivity
Adjusting the potentiometer makes it very versatile. Picks up claps reliably from across the room.

Good module, short cable
The sensor works well with Raspberry Pi GPIO. Wish the included cable was a bit longer, but easy to extend.

Perfect for my alarm project
Works flawlessly with my Arduino Uno. The reverse polarity protection saved me when I wired it backwards initially.
Q: Can this detect specific frequencies?
A: It detects amplitude levels rather than specific frequencies, suitable for claps or loud noises.
Q: Does this work with 3.3V logic?
A: Yes, it operates comfortably between 3.3V and 5V.
Q: Is the output analog or digital?
A: It provides both DO (Digital) and AO (Analog) pins for flexibility.
Q: Is there a library available?
A: It uses standard digital/analog reads, so no specific library is needed, but many example sketches exist online.
Q: Can I adjust the sensitivity?
A: Yes, there is a blue potentiometer on the board to adjust detection threshold.
