Sound Detection Sensor Module Sensors VOS Voice Operated Switch Microphone For Arduino Switches Smart Home |

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 [threshold - sensitivity can be adjusted via potentiometer]

Module features:

2, there is a mounting screw hole 3mm

3, the use 5v DC power supply

4, with analog output

5, there are threshold level output flip

6, high sensitive microphone and high sensitivity.

7, a power indicator light

8, the comparator output is light

This module can detect the intensity of the sound environment, note: the sound sensor can identify the presence of voice(according to the principle of vibration) or a particular frequency of sound,does not recognize the volume of the sound
Sensitivity adjustable,digital potentiometer to adjust (blue)

  Working voltage: 3.3 V to 5V
  Output form, digital switch output (0 and 1, High and low elecrical level)
  Has a fixed bolt hole, convenient installation
 Small board PCB size: 3.2 cm * 1.7cm

  1 The sound module is most sensitive to the ambient sound intensity and is generally used to detect the sound intensity.

  2 When the ambient sound intensity reaches the set threshold, OUT outputs a high level. When the ambient sound intensity exceeds the set threshold, the module OUT outputs a low level;

  3 small-plate digital output OUT can be directly connected with the single-chip, and the high-low level is detected by the single-chip, thereby detecting the sound of the environment;

  4 small board digital output OUT can directly drive our relay module, which can form a voice switch.
