KY-037 Sound Sensor Module, High Sensitivity Microphone for Arduino, Analog & Digital Outpu

The KY-037 is a high-sensitivity microphone sound sensor module that can detect sound intensity and output both analog and digital signals. It includes an electret microphone preamplifier circuit with adjustable sensitivity via an onboard potentiometer. The digital output goes high when the detected sound exceeds the threshold set by the potentiometer, while the analog output reflects real-time sound levels. It’s perfect for DIY sound-activated projects, alarms, and audio detection tasks with microcontrollers

Key Features:

• High-sensitivity microphone for accurate sound detection
• Dual outputs: analog for waveform tracking, digital for threshold detection
• On-board potentiometer to adjust digital output sensitivity
• Compatible with Arduino, Raspberry Pi, and other microcontrollers
• Compact design suitable for DIY electronics and smart automation projects
• Power supply: 3.3V – 5V DC for flexible use
