VKLSVAN 5PCS High Sensitivity Sound Microphone Sensor Detection Module for Arduino AVR PIC

5PCS High Sensitivity Sound Microphone Sensor Detection Module for Arduino AVR PIC

VKLSVAN 5PCS High Sensitivity Sound Microphone Sensor Detection Module for Arduino AVR PIC

Product features: Can detect the sound intensity of the surrounding environment. Note: This sensor can only identify the presence or absence of sound (based on the vibration principle) and cannot identify the size of the sound or the sound of a specific frequency. Adjustable sensitivity (adjusted by the blue digital potentiometer in the figure). Working voltage 3.3V-5V. Output form Digital switch output (0 and 1 high and low levels). Fixing bolt holes are provided for easy installation. Small board PCB size: 32mm * 17mm Module wiring instructions: VCC external 3.3V-5V voltage (can be directly connected to 5v microcontroller and 3.3v microcontroller) GND external GND OUT small board switch output interface (0 and 1) Instructions: 1. The sound module is most sensitive to the sound intensity of the environment and is generally used to detect the sound intensity of the surrounding environment; 2. When the ambient sound intensity does not reach the set threshold, the module OUT outputs a high level. When the ambient sound intensity exceeds the set threshold, the module OUT outputs a low level; 3. The digital output OUT of the small board can be directly connected to the microcontroller, and the high and low levels are detected by the microcontroller to detect the ambient sound; 4. The digital output OUT of the small board can directly drive the relay module of our store, thereby forming a voice-controlled switch; Package contain: 5PCS High Sensitivity Sound Microphone Sensor Detection Module
