KY-038 Microphone Voice Sound Sensor Module

TeknoCrafters FA3020 KY-038 Microphone Voice Sound Sensor Module The TeknoCrafters FA3020 KY-038 Microphone Voice Sound Sensor Module is a compact, dual-output sensor ideal for detecting and responding to sound in electronic projects. Designed for use with platforms like Arduino, Raspberry Pi, and ESP32, this module delivers both analog and digital outputs, providing flexible integration options for sound-responsive applications. Whether you're building a sound-activated system, a voice-triggered interface, or experimenting with acoustic sensors in educational settings, the KY-038 delivers accuracy, simplicity, and versatility in a small package. Key Features Dual Output Capabilities – Offers both analog output for real-time sound level readings and digital output for threshold-triggered responses Onboard Sensitivity Adjustment – Integrated potentiometer allows for fine-tuning the sound threshold of the digital output Broad Operating Voltage – Compatible with 3.3V to 5V systems, making it adaptable across multiple platforms Compact and Lightweight – Easy to embed in DIY electronics, wearables, robotics, and home automation projects Status Indicators – Built-in power and output status LEDs for immediate visual feedback Cross-Platform Compatibility – Seamlessly integrates with Arduino, Raspberry Pi, ESP8266, ESP32, and more Technical Specifications Specification Description Operating Voltage 3.3V to 5V Analog Output Variable voltage reflecting sound level Digital Output HIGH/LOW based on threshold Sensitivity Control Adjustable via onboard potentiometer Interface Pins VCC, GND, AOUT (Analog), DOUT (Digital) Dimensions Compact module format Installation Example In a practical smart home automation scenario, this sensor can be used to implement a sound-activated light system. Mount the FA3020 KY-038 in a room and connect it to a microcontroller. When it detects a clap or voice signal above a preset threshold, the module sends a digital signal to trigger a relay that powers a light fixture. This enhances accessibility and user interaction without physical switches. Benefits for Installers and Technicians Quick Setup – Easily connects with standard jumper wires and breadboards Flexible Functionality – Can be used for event detection or sound level monitoring Adjustable Response – Onboard control lets installers tailor performance to the environment Great for Prototyping – A reliable option for early-stage development or educational training Warranty and Support Tri-Tek Electronics is an authorized distributor of TeknoCrafters products, ensuring full manufacturer warranty coverage, direct factory support, and competitive pricing.
