Advanced Sound Control Sensor with Microphone Amplifier - YANXD (Sound Sensor Blue)

Overview of the Sound Sensor Modules

🛠️ This sound sensor module series, featuring cutting-edge technology components including the MAX4466 and MAX9814 chips, is designed for projects requiring sensitive sound detection and control. Both the Red and Blue sound modules utilize an electret condenser microphone paired with the LM393 for signal processing, showcasing reliability and precision in detecting ambient sound levels.

🔴 Red Sound Module

🪶 The Red sound sensor module measures a compact 32mm x 17mm x 8mm. Operating within a DC 4-6V power range, it outputs a low-level signal when activated by sound. The integrated signal light illuminates when a sound is detected, making it ideal for applications such as acoustic control lights and sound alarms. The maximum induction distance for this module is 0.5 meters, allowing it to effectively sense nearby noises. With its straightforward single-channel output, the Red module is a robust choice for various interactive projects.

🔵 Blue Sound Module

📦 Similar in functionality to its red counterpart, the Blue sound module also boasts a compact size of 32mm x 17mm x 15mm and operates on DC 4-6V. It indicates sound detection through a low-level signal output, accompanied by a lighting indicator. Designed for seamless integration with other sensors, this module can complement photosensitive sensors for advanced lighting control and alarm systems. The maximum induction distance remains 0.5 meters, making it suitable for close-proximity sound detection.
