The KY-037 microphone sensor module is a highly sensitive sound and noise sensor, ideal for detecting sound events or volume changes in electronic projects. Thanks to its integrated amplifier and digital and analog output, the module is perfect for microcontroller platforms such as Arduino, Raspberry Pi, ESP32 and other DIY electronic systems.
Features:
- Model: KY-037 - Highly sensitive microphone module
- Supply voltage: 3.3 V - 5 V D
- Analog output (A0): provides the measured sound pressure level (voltage signal proportional to the volume)
- Digital output (D0): provides HIGH/LOW signal when an adjustable threshold value is exceeded
- Sensitivity: adjustable via potentiometer
- Integrated operational amplifier for precise signal amplification
- LED display for status indication during sound detection
- Dimensions: approx. 38 × 15 × 12 mm
Advantages:
- High sensitivity for sound and speech detection
- Easy integration with microcontrollers (Arduino, Raspberry Pi, etc.)
- Dual output for flexible use in analog or digital signal processing
- Ideal for projects such as speech recognition, sound-activated controls, security or monitoring systems
Application examples:
- Sound-activated LED circuits
- Sound level measurements
- Speech or clap detection
- Audio trigger systems
Scope of delivery:
