Sound Sensor Module


 Microphone Sensor High Sensitivity Sound Detecte Voice Switch Detect Module.

120

Description:

Sound module is sensitive to the environment, generally to be used to detect the intensity of the ambient sound.
If the module can not reach to the threshold set in the environment of sound, OUT output high level. When the ambient sound level exceeds the set threshold, the module OUT output low level;
The digital ouput OUT on the small plates can be directly connected to the microcontroller, detecting the sound environment via the microcontroller detecting high and low level.
The digital ouput OUT on the small plates can directly drive relay module, which works as a voice-activated switch;
Feature:
It’s to be used for detecting the sound intensity of ambient. 2. Adjustable sensitivity (adjusted by the blue digital potentiometers)
Operating voltage 3.3V-5V
Output form: Digital switching outputs ( 0 and 1 high and low Level)
Easy installation with bolt hole
Small PCB Size :(L*W) 3.2* 1.7cm/1.26″*0.67″
