Description
A compact and highly sensitive microphone-based sensor designed for sound and voice detection applications — that is the KY-037 Voice Sound Detection Sensor Module. Equipped with an onboard electret microphone and signal conditioning circuitry, the module can detect surrounding sound intensity and provide output signals for microcontrollers such as Arduino, ESP32, Raspberry Pi, STM32, and other embedded platforms. The module features adjustable sensitivity through an onboard potentiometer, allowing users to fine-tune detection thresholds according to their project requirements. It is commonly used in sound-activated systems, intelligent robots, smart vehicles, security alarms, voice-controlled devi
