The KY-038 Sound Sensor Module is a simple and compact device designed to detect sound levels in the environment using a condenser microphone. It outputs both analog and digital signals, making it perfect for Arduino, Raspberry Pi, and ESP32 based projects.
This sensor is commonly used in sound-activated lights, alarms, voice-controlled automation, and interactive DIY electronics. With an on-board sensitivity potentiometer, it allows users to fine-tune the detection threshold.
Whether you're working on robotics, home automation, or educational kits, the KY-038 makes audio-based sensing easy and affordable.
