Detecting Big & Small Sound using Sound Sensor , Raspberry Pi, Python

Hi,

 I like to share my experience connecting Raspberry Pi , Big & Small Sound Sensor using Python.


Note :
You can use the same circuit , python program for both big and small sound sensors. The process is same for both the sensors 

I.Things Needed :

 1. Raspberry Pi 3 Model B+

 2.  a) Big Sound Sensor

      b) Small Sound Sensor  - KES200

                                   

 3. 3 Female to Female Jumper wires.

II.  Circuit Completion

a) Complete  the circuit has shown below .  

b) When you connect for the first time, you will see two red lights burning

c) Take a screw driver and adjust the screw so that only one light burns and when you knock near the sensor,  second light should blink ( it means sound is detected ).

II.Python Program 

a) Open a Text Editor and give the following program and save it as sound.py :

Python File :

IV. Executing Python program 

a) Open the Terminal using VNC Viewer or Putty / MobaXterm and  give the command

     python sound.py

Big Sound Sensor :

 Now knock near the big sensor

Small Sound Sensor :


Now blow air near  small sound  sensor

Now , you have successfully detected sound using sound sensor ( big and sound ) & Python.
