Sound Detection Sensor Module

Sound Detection Sensor Module

The Sound Sensor Module provides an easy and efficient way to detect sound intensity. It is widely used in security, switch control, and monitoring applications. The module's sensitivity can be adjusted easily, making it convenient for various uses.

The sensor uses a microphone that captures sound and sends it to an amplifier, peak detector, and buffer circuit. When the sound exceeds a preset threshold, the module outputs a digital signal to a microcontroller for further processing.

An onboard LED indicator lights up when the sound level exceeds the set point, making it simple to monitor and debug

Key Features

• Digital signal output indication
• Adjustable sensitivity via onboard potentiometer
• Single-channel digital signal output
• Onboard LED indicators for power and output
• Convenient mounting with bolt holes
• Compact design and low power consumption

Technical Specifications:

Working Principle

The microphone captures ambient sound and feeds it into the LM393 comparator circuit. The sound level threshold is set using the onboard potentiometer. When the input sound level exceeds this set threshold:

• The output pin goes LOW (digital 0).
• The output LED lights up.
