4PCS High Sensitivity Sound Microphone Sensor Detection Module for Arduino AVR PIC

Description:

1.They Can detect ambient sound intensity Attention: the sensor can most effective identify the presence of (in line with the main of vibration) of sound does now not recognize the sound or the dimensions of the actual frequency of sound.

2. Sensitivity adjustable

3. Working voltage:DC 3.3-6V

4. The output form Digital switch output (1 s and 0 s + v)

5. Equipped with a set bolt hole, convenient installation

6. Size:34mm*17mm*15mm(length*width*height)

Mounting screw hole 3mm.
5V DC power provide
There are threshold level output turn.
Real-time output of the microphone voltage signal / DO. when the sound intensity reaches a threshold. Application: Microphone sound detection.
The output low and high signal threshold – Sensitivity potentiometer adjustment.
