High Sensitivity Microphone Sensor Module KY-037

The KY-037 High Sensitivity Microphone Sensor Module is designed for precise sound detection applications. This module integrates a high-quality microphone with an adjustable gain amplifier and comparator to convert ambient sound into a digital or analog signal. Ideal for detecting sound levels in the environment such as claps, speech, or noise events, it offers excellent sensitivity and adaptability for various DIY electronics projects.

The module provides two outputs:

1. Analog Output (A0) – Proportional to sound intensity.

2. Digital Output (D0) – Triggers when sound exceeds a set threshold (adjustable via onboard potentiometer).

Operating at 3.3V to 5V, the KY-037 module is compatible with popular microcontrollers like Arduino, Raspberry Pi, and ESP boards, making it ideal for interactive and sound-responsive systems.

✅ Applications:

• Voice-activated lighting systems.
• Security alarm systems triggered by sound.
• Sound-sensitive robots and interactive toys.
• Noise level monitoring systems.
• DIY electronics and education projects.

✅ Packing List:

• 1x KY-037 High Sensitivity Microphone Sensor Module

✅ FAQ:

Q1: What is the difference between the analog and digital outputs?
A1: Analog output reflects real-time sound level, while digital output triggers only when the sound exceeds a preset threshold.

Q2: Is the sensitivity adjustable?
A2: Yes, using the onboard potentiometer.

Q3: Can it detect speech or clapping?
A3: Yes, the module can detect sudden noises like clapping, knocking, or loud speech.
