The Sound Detection Module Sensor for Intelligent Vehicles, Compatible with Arduino is a single-channel signal output sensor. It responds to low-level sound signals with high fidelity, outputting a low-level signal when sound is detected, accompanied by an indicator light.
This module can be used for various applications such as acoustic control of lighting, sound and light alarms, and sound detection. It works in conjunction with a photosensitive sensor for sound-based control. The maximum detection distance is 0.5 meters.
