Sound Sensor Module – Microphone-Based Audio Detection for Arduino

Description This Sound Sensor Module is designed to detect sound waves using a built-in condenser microphone. It converts sound levels into electrical signals, providing both analog and digital output for flexible interfacing with microcontrollers. The module includes a sensitivity adjustment knob and onboard signal LED. It is ideal for DIY sound-activated projects like clapping lights, voice control systems, and sound alarms using platforms like Arduino or ESP-based boards. Features: High-sensitivity condenser microphone Analog and digital signal outputs Onboard potentiometer to adjust detection threshold Output LED lights up when sound is detected Works on 3.3V to 5V systems Compact and easy to integrate into DIY circuits Suitable for voice-activated switches, alarms, and noise detection Specifications: Operating Voltage: 3.3V – 5V DC Output: Analog (A0) and Digital (D0) Microphone Type: Electret condenser Sensitivity: Adjustable via potentiometer Indicator: Signal detection LED Dimensions: Approx. 32mm x 17mm Mounting Holes: Yes Package Includes: 1 x Sound Sensor Module
