Voice Recognition Module V3 Previous 
The KY-037 Sound Detection Sensor Module is designed for detecting sound or audio signals in the environment. It uses an electret condenser microphone to capture acoustic changes and convert them into an analog voltage signal. The module provides both analog and digital outputs for processing by microcontrollers or other digital circuits. It includes a potentiometer for sensitivity adjustment. A power indicator light is also included. This microphone is not recommended for recording audio.
