 3pin Voice Sound Detection Sensor Module for aduino DIY Intelligent Smart Vehicle Robot Helicopter Airplane Aeroplane Boart Car

 

 

Describe:

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 particular frequency of sound does not recognize the volume of the sound

Sensitivity adjustable digital potentiometer to adjust (blue)3-5 V working voltage 3.3 V

Output form digital switch output (1 s and 0 s + v)

Has a fixed bolt hole, convenient installation

 

 

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 small plate switch output interface (0 and 1)

Sound module sound intensity is the most sensitive to the environment, commonly used to detect the intensity of the sound of the surroundings.

Module in the intensity of the sound environment than set threshold, the OUT output high level, when the intensity of the sound from the outside environment more than set threshold, the module OUT output low level;

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

Small digital output board OUT this shop can be directly driven relay module, which can form a voice-activated switch;
