Sound module

A module description

1 can detect the surrounding environment Sound intensity , Make Note: This sensor can only recognize the presence of sound (according to the principle of vibration) can not recognize the size of the sound or a specific frequency of sound

2 sensitivity adjustable (blue digital potentiometer adjustment)

3 working voltage 3.3V-5V

5 Output form Digital switch output (0 and 1 High and low level )

6 with a fixed bolt hole, easy to install

7 small board PCB size: 3 .4 Cm * 1.6cm

Two-module interface description (4-wire)

1 VCC external 3.3V-5V voltage (can be directly connected with the 5v microcontroller and 3.3v single-chip)

2 GND External GND

3 DO small board digital output interface (0 and 1)

Three instructions

1 sound Module to the environment Sound intensity The most sensitive, generally used to detect the surrounding environment Sound intensity The

2 modules in The ambient sound intensity is less than Set the threshold, DO port output high level, when the external environment Sound intensity When the threshold is exceeded, the module D0 outputs a low level;

3 small board digital output D0 can be directly connected with the microcontroller, through the microcontroller to detect high and low levels, thus to detect the environment sound ;

4 small board digital output DO can directly drive our relay module, which can form a Voice control switch;
