Octopus Analog Noise Sound Sensor Detection Module is a sensor module based on MIC sound sensing element. Sound Sensor is particularly sensitive to sound intensity, and it can be used to detect ambient sound level. Louder noise brings bigger output Sine wave amplitude.

Features:

1. Standard OCTOPUS bricks connector

2. Output Voltage: 3-5V

3. Louder noise brings bigger output Sine wave amplitude.

Quick Start

Hardware Connection

Connect the sound detection sensor module to P1 port on OCTOPUS:BIT.

 

Programming

Click Advanced in the code drawer of MakeCode.

To program for the sound detection sensor, we have to add a package. Find Add Package in the bottom of code drawer and click it. This will pop up a dialogue box. Search "IOT" in the box and click to download this package.

Result

When any sound was detected by the sensor, micro:bit will display the decibel value on the screen.
