Sound Sensor Module KY-037 HW-484 Analog + Digital Output | Adjustable Sensitivity DIY Electronics

Product Description

🔊 Overview This KY-037 / HW-484 Sound Sensor Module lets your microcontroller detect sound levels and trigger responses based on noise intensity. It’s perfect for Arduino, Raspberry Pi, ESP32, ESP8266, and other DIY electronics and robotics projects. 📌 Key Features ✅ Dual Outputs — Analog & Digital • Analog Output (AO): Real-time sound level voltage for measuring intensity. • Digital Output (DO): Triggers HIGH/LOW when sound exceeds a set threshold. ✅ Adjustable Sensitivity Tune the onboard potentiometer to set the sound trigger level you want — ideal for claps, loud noises, or threshold-based sound events. ✅ Easy to Use • Works with 3.3V systems like Arduino, Raspberry Pi, and ESP boards. • Simply connect VCC, GND, AO, and DO to your controller. ✅ Indicator LEDs On-board LEDs show power and detection status for quick visual feedback Part Numbers: KY-037, HW-484 • Operating Voltage: 3.3V DC • Outputs: Analog (AO) + Digital (DO) • Chip: LM393 comparator • Microphone: Electret condenser type for reliable detection • Mounting: Compact board with mounting hole 📦 What’s Included • 1 × Sound Sensor Module (KY-037 / HW-484)
