5PCS Sensitivity Sound Microphone Sensor Detection Module for Arduino AVR PIC Short overview Small, reliable sound detection modules designed for quick integration with microcontroller projects. Each module converts acoustic events into usable signals, making it simple to add clap detection, voice activity sensing, or reactive sound controls to Arduino AVR PIC and similar development boards. Key benefits Fast integration: Readytouse module form lets you connect directly to microcontroller inputs for rapid prototyping and deployment. sensitivity: Detects lowlevel sounds while allowing adjustment so you can tune response to your environment and reduce false triggers. Dualmode output: Provides usable signal types for both simple event detection and more detailed level monitoring, so you can build either triggerbased or analogdriven behaviors. Compact and durable: Small footprint fits into tight enclosures and lightweight projects without affecting layout. Costeffective bundle: Five identical modules let you prototype multiple variants, equip several devices, or keep spares on hand. Features and attributes Function: Detects sound and produces outputs suitable for digital event triggers and analog level monitoring. Compatibility: Designed to work with Arduino AVR PIC and other microcontroller platforms using standard GPIO and ADC inputs. Sensitivity control: Onboard adjustment lets you set the detection threshold to match ambient noise conditions. Indicator: Visual signal shows when sound crosses the set threshold for easy tuning and testing. Size and material: Small circuit board with standard throughhole or header pins for straightforward wiring and mounting in hobby and industrial projects. Performance: Responsive detection of speech, claps, knocks, and other acoustic events with adjustable hysteresis to reduce chatter. Typical applications Home automation: Turn lights on with a clap, trigger scenes with a vocal cue, or add simple hands controls to household devices. Security and monitoring: Detect breaking glass, loud impacts, or abnormal noise levels and send alerts through a connected microcontroller. Robotics and interactive installations: Enable robots or exhibits to react to user sounds, or use sound input to drive animations and effects. Quick integration tips Power module from a stable 3.3 to 5 volt source as supported by your microcontroller. Use the analog output for level visualization and finegrained processing, use the digital output for simple on off triggers. Adjust sensitivity while monitoring the indicator to find the right threshold for your environment. Add basic debounce logic or short software delay to avoid rapid retriggering in noisy settings. What makes this module stand out Pack of five modules provides flexibility for multiunit projects and iteration during development. Simple, proven interface that pairs well with common microcontroller boards for fast testing and productionready integration.
