Overview:
The KY-038 Small Sound Sensor Module is designed to detect sound or noise levels with high sensitivity. It includes a built-in microphone that converts sound waves into electrical signals. The module features both analog and digital outputs, allowing it to measure sound intensity and trigger actions when a certain threshold is reached. It is commonly used in projects like sound-activated systems, noise monitoring, and interactive installations. This module is compatible with platforms like Arduino, Raspberry Pi, and ESP32.
