KY 038 KY-038 4pin Mini Voice Sound Detection Sensor Mic Module for Arduino In Pakistan

KY038 LM393 Sound Detection Sensor Module for Arduino detects whether the sound has exceeded a threshold value. The sound is detected via microphone and fed into a KY 038 LM393 op-amp. The sound level setpoint is adjusted via an onboard potentiometer. When the sound level exceeds the setpoint, an LED on the module is illuminated and the output is sent low.
