Description
The KY-037 High Sensitivity Sound Sensor Module detects sound levels in the environment and outputs both analog and digital signals. Ideal for Arduino, Raspberry Pi, and microcontroller projects that react to sound or voice input.
This module features a high-sensitivity condenser microphone and is perfect for building noise-activated devices, sound-triggered events, or interactive audio-based systems.
