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;
Features:
Its 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
NOTE: This sensor can identify the presence or absence of sound (according to the vibration principle ), but can not recognize the volume of the sound and the frequency of sound
Module wiring instructions:VCC external connect to 3.3V-5V voltage ( can be directly connected to 5v and 3.3v MCU MCU )
GND to be connected to GND
OUT: Switch output interfaces ( 0 and 1 )
Note:Size for manual measurement, there may be a 0 to 2 cm error, belongs to the normal phenomenon.

Description:
Description:1.Add an ear to your project with this well-designed electret microphone amplifier.
2.This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on.
3.This breakout is best used for projects such as voice changers, audio recordingmpling, and audio-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain.
4.Using it is simple: connect GND to ground, VCC to 2.4-5VDC.
The output pin is not designed to drive speakers or anything but the smallest in-ear headphones
5.you'll need an audio amplifier (such as our 3.7W stereo amp) if you want to connect the amp directly
Specification:The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn't nearly
as noisy or scratchy as other mic amp breakouts we've tried!
You can set the gain from 25x to 125x. That's down to be about 200mVpp (for normal speaking volume about 6" away) which is good for attaching to something that expects 'line level' input without clipping, or up to about 1Vpp, ideal for reading from a microcontroller ADC. The output is rail-to-rail so if the sounds
gets loud, the output can go up to 5Vpp!
For the best performance, use the "quietest" supply available (on an Arduino, this would be the 3.3V supply). The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled). If the audio equipment you're using requires AC coupled audio, place a 100uF capacitor between the output pin and the input of your device. If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF cap is not required.
