LM393- Electret Microphone Module LOAD Cell Operating Voltage 1LM393 Electret Microphone module uses LM393 as its main Op Amp and is a single channel signal output sensor module. LM393 module has 3 pins which are Out, GND and VCC. GND is connected to the ground and VCC is connected to the positive terminal of the power supply. Out is an Output pin. Out pin is high when it does not detect any sound. It goes low whenever it detects sound in its surroundings. Out pin is connected to the digital pin of the
