Sound Detection Sensor LM393 Chip
                                    R14.90  Inc VAT                                
                                                    LM393 Sound Detection Sensor Module for controller detects whether the sound has exceeded a threshold value. The sound is detected via a microphone and fed into an LM393 op-amp. The sound level setpoint is set via an onboard potentiometer.
Can be used for Acoustic control light; give sound and light alarm working with Photosensitive sensor
Note: The Maximum induction distance is 0.5M
