Product Introduction
The KY-037 High-Sensitivity Microphone Module is an analog/digital signal sensor that use a condenser microphone to monitor changes in ambient noise. It captures even the slightest sound fluctuations and converts them into electrical signal outputs. This module is widely used in various applications requiring sound detection, such as smart homes, voice control systems, and sound alarm devices. The KY-037’s high sensitivity enables it to accurately respond to diverse sounds in the environment, providing users with a reliable sound monitoring solution.
advantage of KY-037
- Integrated analog and digital outputs
- Adjustable sensitivity
- Built-in LM393 comparator
- Easy connectivity
- Low cost
Component Composition of KY-037
The KY-037 consists of a CMA-6542PF electret condenser microphone, an LM393 differential comparator for controlling digital output, a BAOTER3296W potentiometer for adjusting the detection threshold, 6 resistors, 2 LEDs, and 4 male pins. The CMA-6542PF electret condenser microphone captures sound waves, while the LM393 differential comparator compares the captured audio signal against a preset threshold to generate a digital output.
The BAOTER3296W potentiometer allows users to adjust the sound detection sensitivity as needed. Turning clockwise increases sensitivity, while counterclockwise reduces it. The 6 resistors provide current limiting and protection within the circuit. The 2 LEDs typically indicate the module’s operational status, such as lighting up when sound detection is successful.The 4 male pins make it convenient for users to connect the KY-037 module to other circuits or microcontrollers, like Arduino, enabling further development and application.
