High sensitivity sound detection module

Model: KY-037.
High sensitivity sound sensor module.
The high-sensitivity sound detection module consists of an analog/digital sensor that uses a microphone condenser to observe changes in ambient noise. Generally used to detect sound above certain levels. It has a potentiometer to set the noise detection threshold.
The digital output provides a HIGH signal when a sound above the threshold is detected. The analog output displays values that represent the noise levels detected by the condenser microphone, the values are relative to the voltage provided and the position of the potentiometer, making it difficult to reconstruct the audio from the values obtained.
This module is compatible with popular microcontroller platforms such as Arduino, ESP32, ESP8266 and Raspberry Pi.
This module has a CMA-6542PF electret condenser microphone, an LM393 differential comparator to control the digital output, a 3296W potentiometer to adjust the detection threshold, 6 resistors, 2 LEDs and 4 male header pins. The module has analog and digital outputs.
Operating voltage: 3.3 V ~ 5.5 V.
Microphone sensitivity: -42 ±3 db.
Current consumption: ~0.5 mA.
Board dimensions: 15 mm x 36 mm.
