Perfect for Clap Switch
Used this for a home automation clap switch. Very responsive and easy to calibrate with the potentiometer.

Good Sensitivity
Works well with Arduino Uno. Only downside is the connector wires are a bit stiff.

Solid Component
Not for voice recognition but great for noise detection. Shipping was fast.
Q: Is a library required?
A: No library needed, just read the analog pin value.
Q: Can it detect decibels?
A: It outputs voltage proportional to sound, not calibrated dB values.
Q: Can I use this outdoors?
A: It is not weatherproof. Please enclose it if using outside.
Q: Does this support digital output?
A: This module is primarily analog, some versions have DO but this SKU is AO.
Q: What is the sampling rate?
A: Depends on your microcontroller ADC, the sensor itself is continuous.
