Microphone sound detection module
For sound detection Module has two outputs:
1. AO, analog output, real-time output voltage signal of the microphone
2. DO, when the sound intensity reaches a certain threshold, the output high and low signal
The threshold-sensitivity can be adjusted via potentiometer on the sensor
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)
Interface definition:
AO: analog output sensor
GND: ground
VCC: Power supply input range: 3V-24V.
DO: Digital Output (comparator output)
Two red LED indication: POWER and SENSOR. POWER: Power is off. SENSOR: When the microphone senses sound reaches a certain value, this LED light.
