Perfect for my Arduino project
This sensor works exactly as described. The analog output is smooth and the sensitivity potentiometer makes it easy to calibrate for different noise levels. Great value for the price.

Great for learning
Bought this for a university electronics class. It's straightforward to wire up and the code examples found online work immediately with this specific board.

Solid performance
Does what it says on the tin. The analog signal correlates well with actual sound pressure. Only minor issue is the soldering pads are a bit small for thick wires.

Excellent detection range
I was surprised by how well this picks up sound from across the room. Using it to trigger LED strips based on music beats. Highly recommended for hobbyists.

Good sensitivity, needs calibration
The module is very sensitive out of the box. I had to spend a few minutes adjusting the pot to ignore background hum, but once set, it detects claps and voices perfectly.

Reliable and compact
Used this in a voice-activated robot build. The form factor is small enough to fit inside the chassis, and the 5V logic level matches my microcontroller directly.
Q: Is the output digital or analog?
A: This specific model provides an Analog Output (AO). There is a separate version of this board available that includes a comparator for Digital Output (DO), but this listing is for the Analog version only.
Q: Can I use this with a 3.3V microcontroller like ESP32?
A: Yes, you can power it with 3.3V, though the sensitivity might be slightly reduced compared to 5V. The analog output will scale with the supply voltage, so it remains compatible with 3.3V ADC inputs.
Q: Can this sensor detect specific frequencies or just overall volume?
A: This module outputs an analog voltage proportional to the overall sound intensity (amplitude). It does not perform frequency analysis on its own; you would need to process the signal with a microcontroller for FFT analysis.
Q: What is the maximum voltage I can supply without damaging it?
A: The module is designed for 5V operation. We recommend staying between 4.5V and 5.5V. Supplying higher voltages, such as 9V or 12V, may damage the onboard components.
Q: Does it come with header pins pre-soldered?
A: No, the module typically ships without header pins soldered to allow for flexible mounting options. You will need to solder your own 3-pin headers to connect it to breadboards or wires.
