Grove - Sound Sensor

The Grove Sound Sensor is a compact, versatile module designed to detect sound levels in the surrounding environment, making it an ideal resource for STEM-based learning in classrooms. Using an onboard LM386 power amplifier and an electric microphone, it translates ambient noise into measurable output. The sensor includes a potentiometer that enables users to fine-tune the sensitivity, offering more control over the detection threshold. Whether you're building a sound-activated light display or exploring audio signals, this sensor offers reliable performance in a small footprint. Its plug-and-play design using the Grove system eliminates the need for complex wiring, making it perfect for beginner-friendly electronics and coding projects.
