KY-037 High Sensitivity Sound Detection Sensor Module – Microphone Sensor for Arduino, AVR, PIC, and Microcontroller Projects
KY-037 High Sensitivity Sound Detection Sensor Module – Microphone Sensor for Arduino, AVR, PIC, and Microcontroller Projects
The KY-037 High Sensitivity Sound Sensor Module is a powerful audio detection module designed to pick up sound signals from the environment and convert them into electrical signals for microcontroller use. Equipped with a built-in electret condenser microphone and dual output modes (analog and digital), this sensor is ideal for sound-activated systems, voice-responsive projects, and noise-level monitoring.
This module is compatible with Arduino, AVR, PIC, Raspberry Pi, and other microcontrollers, making it a great choice for hobbyists, educators, and developers working on interactive or automation projects.
🔊 Key Features:
High Sensitivity Microphone: Detects sound intensity and converts it into a corresponding voltage signal
Dual Output Pins:
Analog Output (A0): Provides real-time voltage signal relative to the sound amplitude
Digital Output (D0): Sends a HIGH or LOW signal based on a sound threshold set via the onboard potentiometer
Onboard Potentiometer: Allows you to adjust the sound threshold for the digital output
Indicator LED: Lights up when the detected sound exceeds the threshold (useful for quick visual feedback)
4-Pin Interface: VCC, GND, A0 (Analog), D0 (Digital)
Operating Voltage: 3.3V to 5V – suitable for a wide range of development boards

Special Offer for New Customers!!
New customers receive a special introductory discount on their first PCB layout/design project.
This allows us to review your design requirements and build a long-term working relationship.
How to Request a PCB Layout / Design
- Send your complete schematic or diagram via our Facebook page.
- Our team will review your diagram carefully to understand the design scope and requirements.
- A detailed quotation will be provided based on:
-
- Design complexity
- Board size and number of layers
- Components and package types
- Special routing or manufacturing requirements
📌 Providing your diagram is essential so we can give you an accurate and fair quotation.
PCB Layout & Design Requirements
To ensure quality and accuracy, please note the following:
- All schematics must be clear, complete, and properly labeled
- Specify:
- Board dimensions (if available)
- Number of PCB layers
- Preferred components or footprints (if any)
- Hand-drawn, unclear, or incomplete schematics are not accepted
- Rush or urgent requests may incur additional charges
What’s Included in the Design Package
Each completed project includes the following deliverables:
✅ 2D PCB layout images
✅ 3D PCB render images
✅ PCB Gerber files (ready for fabrication)
✅ Bill of Materials (BOM)
✅ Component Placement List (CPL / Pick-and-Place file)
✅ Wiring diagram (PDF)
✅ PCB board layout (PDF)
All files are prepared to be manufacturer-ready and easy to review.
Pricing Information
Pricing is project-based and depends on:
- The submitted schematic or diagram
- Board size and layer count
- Types of components used (SMD, through-hole, fine-pitch, BGA, etc.)
- Design complexity and routing difficulty
📌 Final pricing is confirmed only after reviewing the client’s diagram.
Design Review & Approval Process
Before final delivery:
- The client will receive preview files for checking
- Please review carefully for:
- Errors
- Missing information
- Clarifications or revisions
- Once the design is confirmed and approved, the final files will be sent to the client’s email
⚠️ After final approval, any major changes may be treated as a new request.
