3 Pin Sound Detection Sensor Module Voice Airplane Car for Arduino DIY KIT

Characteristics:
Can detect the intensity of the sound environment, use note: the sound sensor can identify the presence of (according to the principle of vibration) or a certain frequency of sound does not recognize the volume of the sound

Sensitivity adjustable digital potentiometer to adjust (blue)

Working voltage 3-5 V 3.3 V.

Digital switching output (1 s and 0 s + v)

Has a fixed bolt hole, easy installation

PCB size small board: 3.2cm * 1.7cm

Module wiring instructions

VCC voltage is 3.3 V to 5 V converter (which can be directly connected to 5 V single-chip microcontroller and 3.3 V)

GND external GND

OUT of the output interface of the small plate switch (0 and 1)

Three instructions

The sound intensity of the sound module is most sensitive to the environment and is often used to detect the intensity of the sound of the environment.

Module in the intensity of the sound environment than set threshold, the OUT output high level, when the intensity of the sound of the outdoor environment exceeds the set threshold, the module OUT output low level;

Small digital output card OUT can be connected directly to the microcontroller, through a single chip microcomputer to detect the high and low level and thus detect the sound environment;

Small digital output card OUT of this store can be a direct driven relay module, which can form a voice activated switch;
