Sound Detection Sensor for Arduino

The Sound Detection Sensor combines a microphone and processing circuitry.

It has the ability to detect different decibles of sound and can be used for anything from industrial to hobby.

Description:
 
Can detect the intensity of the sound environment and the presence of sound (according to the principle of vibration) or a particular frequency of sound does not recognize the volume of the sound.
Adjustable sensitivity with digital potentiometer
working voltage 3.3-5V
Output form: digital switch output (0 and 1)
Has a fixed bolt hole
Dimensions: 3.2 cmx1.7 cm
 
Wiring:
 
VCC voltage is 3.3 V to 5 V converter (which can be directly connected to 3.3 V or 5 V single-chip microcontroller)
GND external to GND
OUT of small plate switch output interface (0 and 1)
 
Instructions:
 
Used to detect the intensity of sound in your surroundings.

The sound level setpoint is adjusted via an onboard potentiometer. When the sound level exceeds the set point, an LED on the module is illuminated and the output is sent low.

This Mic Sound Detection Sensor Module for Arduino detects whether sound has exceeded a threshold value. The sound is detected via microphone and fed into an LM393 op-amp.
