Description
Its Sound detection Sensor module which has 4 pins which are Analog output , GND, Digital , VCC. GND is connected to the ground and VCC is connected to the positive terminal of the power supply. There is a potentiometer onboard to calibrate the digital output of the module. By potentiometer, a threshold volume can be set and when this threshold volume is exceeded status LED will light up and digital output will be low. The other LED glows when the device is powered. Applications like voice switch Projects and loudness level indicator.
