Welcome to Sound sensor repository

Sound sensor

1. Description of Pin

1-1  Position of pin

2. Potentiometer

2-1 Position of Potentiometer

It is necessary to adjust the potentiometer of the sound sensor module to optimize the sensitivity.

3.Power indicator light

3-1 Position of indicator light

3-2  Schematic

This power indicator will illuminate when the module is powered normally.

4.Switch indicator light

4-1 Position of indicator light

4-2  Schematic

When the sound level reaches the set threshold, this indicator will be illuminated, indicating that the module has recognized the sound in the current environment.

5.Sound receiving head

5-1 Position of receiving head

5-2  Schematic

The module receives sound by it, and the sound needs to face the receiver to obtain the best experimental results.

6.MCU

6-1 Position of MCU

This master chip of module.

Hardware connection: (The definition of the pin can be changed in the program by yourself)

1.Connect to Arduino board.

2.Connect to Micro:bit board.

 We will provide Arduino, Micro:bit driver source code.
