Sound detection sensor module

*Can detect the intensity of ambient sound, using Note: This sensor can only recognize the presence or absence of sound (vibration according to the principles of) does not recognize the size of the sound or the sound of a particular frequency
*Sensitivity adjustable (shown in blue digital potentiometer adjustment)
*Operating voltage: 3.3V-5V
*Output form of digital switching output (0 and 1 high-low)
*With the retaining bolt hole, convenient installation.
*Small PCB board size: 3.2cm * 1.7cm
Secong,module wiring instructions:
*VCC external 3.3V-5V voltage (can be directly connected to 5v and 3.3v MCU MCU)
*GND external GND *
OUT small plate switch output interface (0 and 1)
Third, instructions:
*Sound module sound intensity most environmentally sensitive, generally used to detect the intensity of the ambient sound.
*Module reach the set threshold environmental sound intensity, OUT output high, when the ambient sound level exceeds the set threshold, the module OUT output low;
*Small plates OUT digital output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting a sound environment;
