This is a high sensitive microphone with sensor detection module and compatible with Arduino. Features dual outputs and Sensitivity potentiometer adjustment for threshold-sensitivity.
For sound detection, Module has two outputs:
AO, analog output, real-time output voltage signal of the microphone
DO, when the sound intensity reaches a certain threshold, the output high and low signal
LED1: Shows that the sensor is supplied with voltage
LED2: Shows that a magnetic field was detected
- High Sensitivity Sound Microphone Sensor Detection Module
- AO, analog output, real-time output voltage signal of the microphone
- DO, when the sound intensity reaches a certain threshold, the output high and low signal

Included with the package:
- Arduino Compatible High Sensitivity Microphone Sensor Module x 1
Connecting to the Arduino:
- Pin + to Arduino 5+
- Pin - to Arduino -
- Pin A0 to Arduino A0 (for analog program)
- Pin D0 to Arduino 13 (for digital program)
Functionality of the sensor:
The sensor has 3 main components on its circuit board. First, the sensor unit at the front of the module which measures the area physically and sends an analog signal to the second unit, the amplifier. The amplifier amplifies the signal, according to the resistant value of the potentiometer, and sends the signal to the analog output of the module. The third component is a comparator which switches the digital out and the LED if the signal falls under a specific value. You can control the sensitivity by adjusting the potentiometer.
Please note: The signal will be inverted; that means that if you measure a high value, it is shown as a low voltage value at the analog output.
