KY-037 High Sensitivity Sound Microphone Sensor

Size:32mm*17mm*8mm(length*width*height)

Main chip:LM393, Electret condenser microphone

Working voltage: DC 4-6V

Signal output indication

Single channel signal output

The output effective signal is low level

When there is sound, outputs low level and the signal light

Can be used for Acoustic control light , give sound and light alarm working with Photosensitive sensor ,and sound control, sound detect

Circuit board output switch quantity

Note: The Maximum induction distance is 0.5

Sound Detection Sensor Module

A product features:1. Can detect the sound intensity of the surrounding environment, use Note: This sensor can only identify the presence of sound (according to the principle of vibration) can not recognize the size of the sound or a specific frequency of sound2. Adjustable sensitivity (blue digital potentiometer adjustment)3. Operating voltage 3.3V-5V5. Output form Digital switch output (0 and 1 high and low level)6. With fixed bolt holes, easy to install7. Small board PCB size: 3.2cm * 1.7cmTwo module wiring instructions1.VCC external 3.3V-5V voltage (can be directly connected with the 5v microcontroller and 3.3v single-chip)2.GND external GND3.OUT small board switch output interface (0 and 1)Three instructions1. Sound module is the most sensitive to the sound intensity of the environment, generally used to detect the sound intensity of the surrounding environment.2. When the ambient sound intensity reaches the set threshold, the OUT output high level, when the external ambient sound intensity exceeds the set threshold, the module OUT output low;3. Small board digital output OUT can be directly connected with the microcontroller, through the microcontroller to detect high and low levels, which to detect the sound of the environment;
