🔊 KY-037 High Sensitivity Sound Sensor Module 🔊
The KY-037 is a high-sensitivity sound detection module based on an electret microphone. It provides both a digital output (DO) that triggers when the sound level exceeds a threshold, and an analog output (AO) that reflects the relative sound intensity. Perfect for Arduino, Raspberry Pi, and other microcontroller projects requiring sound detection.
✅ Technical Specifications:
- Model: KY-037.
- Sensor Type: High-sensitivity electret microphone.
- Operating Voltage: 3.3V – 5V DC.
- Outputs:
- Digital Output (DO): Active when sound exceeds threshold (adjustable via potentiometer).
- Analog Output (AO): Proportional to sound level.
- Sensitivity: Adjustable via onboard potentiometer.
- Module Size: ~35 × 15 mm.
- Approximate Weight: 4 g.
🔹 Key Features:
✔ Dual output: digital and analog.
✔ Adjustable sensitivity for various applications.
✔ Compatible with Arduino, Raspberry Pi, and other controllers.
✔ Ideal for sound detection and alarm systems.
✔ Compact and lightweight design.
📌 Common Applications:
- Sound-activated alarm systems.
- Clap-controlled lighting or devices.
- Robots that respond to audio cues.
- Noise level monitoring.
- Educational and experimental electronics.
