Microphone Sound Detection Sensor Module

Description

Product Features:1. The intensity of the ambient sound can be detected, the use Note: This sensor can identify the presence or absence of sound (in accordance with the principles of the vibration) does not recognize the size of the sound or the sound of a particular frequency2. Sensitivity adjustable (shown in blue digital potentiometer adjustment)3. Operating voltage 3.3V-5V5. Output in the form of digital switching outputs (0 and 1 high-low)6. A fixed bolt holes for easy installation7. small plate PCB size: 3.2cm * 1.7cmTwo module wiring instructions1.VCC external 3.3V-5V voltage (which can be directly connected to 5v and 3.3v MCU MCU)2.GND external GND3.OUT small plate switch output interfaces (0 and 1)Three instructions1. sound module most sensitive to environmental sound intensity, sound intensity is generally used to detect the surrounding environment.2. Module reach the set threshold ambient sound intensity, OUT output high, when the ambient sound level exceeds the set threshold, the module OUT output low;3. Small board digital output OUT can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting a sound environment;
