FAQ — Sound Sensor Module
Q: Analog output available?
A: This module's output is digital (threshold-based). For analog amplitude output, use a different microphone breakout board with built-in op-amp.
Q: Useful range?
A: Ambient sound triggering typically works within 1-3m radius. Adjust sensitivity via the onboard potentiometer for your specific environment.
Q: Bulk pricing?
A: Yes — email contact@lys-sz.com.
